- Pulse position modulation refers to pulse position modulation (Pulse Position Modulation, PPM), differential pulse position modulation (Differential Pulse Position Modulation, DPPM), digital pulse interval modulation (Digital Pulse Interval Modulation, DPIM) and various combinations thereof.
- PPM Pulse Position Modulation
- DPPM differential pulse position modulation
- DPIM Digital Pulse Interval Modulation
- Various pulse position modulation methods evolved. Generally speaking, pulse-type position modulation can achieve relatively high power efficiency, simple modulation method, and easy hardware circuit implementation. However, the disadvantages are poor performance against channel interference and low frequency band utilization. The following takes several typical pulse-type position modulations as examples to illustrate.
- PAM is a modulation method in which the amplitude of the pulse carrier changes with the baseband signal.
- This modulation system is simple to implement and can be demodulated based on a non-coherent demodulator.
- Figure 2 shows a schematic diagram of second-order PAM modulation. High level is used to represent "1" and low level is used to represent "0". This modulation method can also be called on-off keying (On- off Keying (OOK) or binary amplitude keying (Amplitude Shift Keying (ASK)).
- OOK On- off Keying
- ASK Binary amplitude Shift Keying
- Figure 3 shows a schematic diagram of fourth-order PAM modulation.
- a fourth-order amplitude pulse signal is used to carry information bits. Each pulse signal can carry two information bits.
- PPM is a modulation method with simple coding and high power efficiency.
- PPM modulation modulates the relative position (i.e. phase) of a pulse in a signal pulse sequence, so that the relative position of the pulse changes with the baseband signal, but the amplitude and width of each pulse in the sequence remain unchanged.
- Figure 4 is a schematic diagram of 8-PPM modulation, each frame is divided into 8 time slots, and pulse signals are only sent on one time slot within a frame at a time, and the amplitudes of these pulses are the same, and by changing these
- the relative position of the pulses on the time slot within the frame carries the information bits to achieve modulation. In the first frame, if the pulse is sent on the 5th time slot, the pulse can carry the bit "100"; in the second frame, if the pulse is sent on the 2nd time slot, the pulse can carry the bit "001".
- MPPM Multiple Pulse Position Modulation
- MPPM is one of the optimized modulation methods of traditional PPM modulation and has higher frequency band utilization. Unlike PPM modulation, which only sends one pulse on one time slot of each frame, MPPM modulation modulates the relative positions (i.e., phases) of multiple pulses in the signal pulse sequence, so that the relative positions of the multiple pulses change with the baseband signal. However, the amplitude and width of each pulse in the sequence remain unchanged.
- Figure 5 shows a schematic diagram of 2-pulse 8-PPM modulation, which is denoted as (8,2)-MPPM for simplicity. Each frame is divided into 8 time slots. Different pulse signals are sent on the two time slots in the same frame each time, and the relative position arrangement and combination of the two pulses on the time slots within the frame are changed to achieve modulation.
- log 2 28 4.8 bits can be carried in one frame, while traditional 8-PPM transmits 3 bits in one frame. Therefore, MPPM can achieve data transmission with higher frequency band utilization.
- MPAPM Multiple Pulse Amplitude Position Modulation
- MPAPM is one of the improved methods of MPPM modulation. Based on MPPM, information modulation is achieved by modulating the amplitude of each pulse, thereby further improving the frequency band utilization of the system.
- Figure 6 shows a schematic diagram of the fourth-order PAM-(8,2)-MPPM modulation. The amplitude of the pulse on the time slot is one of four amplitudes. Therefore, these two pulses can add an additional 4 to the MPPM. bits, so 8.8 bits can be carried in one frame.
- FIG. 7 is a schematic diagram of DPPM modulation. The low level before a single pulse is retained and the low level after the single pulse is removed. Therefore, compared with PPM, under the premise of the same number of time slots, DPPM modulation has a higher duty cycle; during the same information transmission process, DPPM modulation occupies less bandwidth than PPM, improving data transmission. efficiency.
- pulse position modulation PPM in addition to the above-mentioned MPPM, MPAPM, and DPPM modulation, there are many other variants, including: Overlapping Pulse Positioning Modulation (OPPM), Double-width Pulse Position Modulation (Dual Duration) Pulse Positioning Modulation, DDPPM), Dual Amplitude Pulse Positioning Modulation, DAPPM, Shorten Pulse Position Modulation, SPPM, Separated Double Pulse Positioning Modulation, SDPPM, etc. .
- OPPM Overlapping Pulse Positioning Modulation
- DDPPM Double-width Pulse Position Modulation
- DAPPM Dual Amplitude Pulse Positioning Modulation
- SPPM Separated Double Pulse Positioning Modulation
- SDPPM Separated Double Pulse Positioning Modulation
- the pulse modulation discussed previously is based on pulse position, but another option is to load information by using the number of empty time slots between two adjacent pulses instead of the absolute position of the pulse.
- the number of time slots included in the DPIM frame symbol is not fixed.
- the DPIM symbol is represented by the starting time slot pulse and several nearby empty time slots.
- the number of empty time slots is determined based on the decimal data corresponding to the binary source. determination.
- L-DPIM the log 2 2L bits of each frame symbol are mapped into L possible symbol structures, and the symbol lengths are different.
- the minimum and maximum symbol lengths are T s and L ⁇ T s respectively, where T s is Single slot size.
- Figures 8 and 9 show 4DPIM modulation schematics.
- Figure 8 is a DPIM modulation schematic without protected time slots
- Figure 9 is a DPIM modulation with protected time slots.
- DPIM modulation In addition to single-pulse DPIM modulation, there are many variants of DPIM modulation, such as Double-headed Pulse Interval Modulation (DH-PIM), Dual Pulse Pulse Interval Modulation (DPPIM), Dual-amplitude Pulse Interval Modulation (DAPIM), Fixed-length Digital Pulse Interval Modulation (FDPIM), Fixed-length Dual-amplitude Pulse Interval Modulation, FDAPIM), etc.
- DH-PIM Double-headed Pulse Interval Modulation
- DPPIM Dual Pulse Pulse Interval Modulation
- DAPIM Dual-amplitude Pulse Interval Modulation
- FDPIM Fixed-length Digital Pulse Interval Modulation
- FDAPIM Fixed-length Dual-amplitude Pulse Interval Modulation
- Both single-dimensional modulation and two-dimensional modulation can improve frequency band utilization based on high-order modulation, but the problem is that as the modulation order increases, the Euclidean distance of the constellation points in the Euclidean space decreases, so the probability of decision error occurs Increase. Because in order to ensure the BER performance of high-order modulation, not only the system is required to work in a high SNR scenario, but also the demodulation end needs to determine the reference constellation point based on the pilot signal sent by the transmitter. Otherwise, poor demodulation performance will occur, which requires sending The terminal sends pilot reference signals that can carry all constellation points. Therefore, the traditional method of improving spectral efficiency based on high-order modulation has high requirements on system overhead, power consumption, and implementation complexity. Pulse modulation, including pulse position modulation and pulse interval modulation, has the disadvantage of low frequency band utilization. In addition, traditional modulation rarely pays attention to transmission reliability, making the system sensitive to noise, channel attenuation, and interference.

本申请属于通信技术领域,具体涉及一种调制方法、装置及通信设备。
如何提高通信***的频带利用率一直是通信领域关注的重点,高阶调制是提升频谱效率有效方式之一。按照调制在调制维度上的区别可以分为单维调制和二维调制,其中典型的单维调制包括:二进制振幅键控(Amplitude Shift Keying,ASK)、频移键控(Frequency-shift keying,FSK)、相移键控(phase-shift keying,PSK)调制等;而二维调制则有正交幅度调制(QAM,Quadrature Amplitude Modulation)、幅度相移键控(Amplitude Phase Shift Keying,APSK)等调制。单维调制和二维调制都可以基于高阶调制来提高频带利用率,但带来的问题是随着调制阶数的提高,星座点在欧式空间上的欧式距离减少,因此产生判决误差的概率增加。因为为了保证高阶调制的误比特率(Bit Error Ratio,BER)性能,不仅要求***工作在高信噪比(Signal to Noise Ratio,SNR)场景,并且解调端需要根据发送端发送的导频信号来确定参考星座点,否则会发生解调性能差,这就需要发送端发送能够携带所有星座点的导频参考信号。因此传统基于高阶调制来提高频谱效率的方式对***开销、功耗和实现复杂度都有较高的要求。另外传统的调制很少关注于传输可靠性,导致***对噪声、信道衰减、干扰敏感。
因此,如何基于调制获得较高频带利用率或可靠性的同时,能够降低***SNR的要求,同时简化收发端的实现复杂度是需要解决的。

除了传统的基于电磁波的幅度、相位、频率等维度进行调制的单维调制和二维调制,脉冲类调制是无线光通信、激光通信等通信***中应用比较广泛的调制方式。脉冲类位置调制是指脉冲位置调制(Pulse Position Modulation,PPM),差分脉冲位置调制(Differential Pulse Position Modulation,DPPM),数字脉冲间隔调制(Digital Pulse Interval Modulation,DPIM)及其各种组合以及由此演变而成的各种脉冲位置调制方式。总体来说,脉冲类位置调制可以获得比较高的功率效率、且调制方式简单、硬件电路实现方便。但缺点在于对抗信道干扰性能较差,且频带利用率较低。下面以几种比较典型的脉冲类位置调制为例进行说明。
(一)脉冲幅度调制(Pulse Amplitude Modulation,PAM)
PAM是一种脉冲载波的幅度随基带信号变化的一种调制方式。该调制方式***实现简单,并且可以基于非相干解调器实现解调。如图2所示为2阶PAM调制的示意图,用高电平表示“1”,用低电平表示“0”,该调制方式也可以叫做开关键控(On-
off Keying,OOK)或二进制振幅键控(Amplitude Shift Keying,ASK)。图3所示为4阶PAM调制示意图,用4阶幅度的脉冲信号来承载信息比特,每个脉冲信号都可以携带两个信息比特。
(二)脉冲位置调制
PPM是一种编码简单、功率效率高的调制方式。PPM调制通过调制信号脉冲序列中一个脉冲的相对位置(即相位),使该脉冲的相对位置随基带信号变化,但序列中各脉冲的幅度和宽度均不变。如图4所示为8-PPM调制的示意图,将每个帧分成8个时隙,每次只在一个帧内的一个时隙上发送脉冲信号,并且这些脉冲的幅度相同,并且通过改变这些脉冲在帧内时隙上的相对位置来携带信息比特,从而实现调制。第一帧内,脉冲在第5个时隙上发送,则该脉冲可以携带比特“100”;第二帧内,脉冲在第2个时隙上发送,则该脉冲可以携带比特“001”。
(三)多脉冲位置调制(Multiple Pulse Position Modulation,MPPM)
MPPM是传统PPM调制的优化调制方式之一,并且具有更高的频带利用率。不同于PPM调制中只在每一帧的一个时隙上发送一个脉冲,MPPM调制通过调制信号脉冲序列中多个脉冲的相对位置(即相位),使多个脉冲的相对位置随基带信号变化,但序列中各脉冲的幅度和宽度均不变。如图5所示为2-pulse 8-PPM调制示意图,为了简便记为(8,2)-MPPM。每一帧内分成8个时隙,每次同一个帧内的两个时隙上发送不同的脉冲信号,并且改变这两个脉冲在帧内时隙上的相对位置排列组合来实现调制。每一帧内8个时隙上的2个脉冲之间的相对位置排列组合个数为因此一帧内可以携带log228=4.8个比特,而传统8-PPM在一帧内则传输3比特。因此,MPPM能够实现更高频带利用率的数据传输。
(四)多脉冲位置-幅度调制(Multiple Pulse Amplitude Position Modulation,MPAPM)
MPAPM是MPPM调制的改进方式之一,在MPPM的基础上通过调制每个脉冲的幅度来实现信息调制,从而进一步提高***的频带利用率。如图6所示为4阶PAM-(8,2)-MPPM调制示意图,时隙上脉冲的幅度为四种幅度中的一种,因此这两个脉冲可以在MPPM上的基础上额外增加4个比特,因此一帧内可以携带8.8个比特。
(五)差分脉冲位置调制
PPM在信息传输过程中占用带宽较大,造成一定程度的浪费。DPPM调制是一种改进的PPM调制方式,如图7所示为DPPM调制示意图,保留单个脉冲之前的低电平、去掉单个脉冲之后的低电平。因此相比于PPM来说,在相同的时隙数的前提下,DPPM调制方式具有更高的占空比;在相同的信息传输过程中,DPPM调制所占用带宽比PPM减少,提高了数据传输效率。
脉冲位置调制PPM中,除了上述提到的MPPM、MPAPM、DPPM调制之外,还有其它的很多变种,包括:重叠脉冲位置调制(Overlapping Pulse Positioning Modulation,OPPM)、双宽脉冲位置调制(Dual Duration Pulse Positioning Modulation,DDPPM)、双幅度脉冲位置调制(Dual Amplitude Pulse Positioning Modulation,DAPPM)、缩短脉冲位置调制(Shorten Pulse Positioning Modulation,SPPM)、分离双脉冲位置调制(Separated Double Pulse Positioning Modulation,SDPPM)等。
(六)数字脉冲间隔调制
前面讨论的脉冲调制都是基于脉冲位置的,然而通过利用两个相邻脉冲之间的空时隙数目来来取代脉冲的绝对位置来加载信息也是另外一种选择。DPIM帧符号中所包含的时隙个数不是固定的,DPIM符号由起始时隙脉冲和其后附近的若干个空时隙表示,空时隙的个数根据二进制信源对应的十进制数据来判定。在L-DPIM中,每帧符号的log22L位被映射成L种可能的符号结构,并且符号长度不同,最小及最大的符号长度分别为Ts和L·Ts,其中,Ts为单个时隙大小。为了尽可能降低数据传输过程中码间干扰的影响,在每个DPIM符号后面加上一个保护时隙,这样最小和最大符号长度分别为2Ts和(L+1)·Ts。图8和图9给出了4DPIM的调制示意图,其中,图8为无保护时隙下的DPIM调制示意图,图9为有保护时隙下的DPIM调制。
除了单脉冲的DPIM调制之外,还有很多DPIM调制的变种,比如双头脉冲间隔调制(Double-headed Pulse Interval Modulation,DH-PIM)、双脉冲间隔调制(Dual Pulse Pulse Interval Modulation,DPPIM)、双幅度脉冲间隔调制(Dual-amplitude Pulse Interval Modulation,DAPIM)、定长数字脉冲间隔调制(Fixed-length Digital Pulse Interval Modulation,FDPIM)、定长双幅度脉冲间隔调制(Fixed-length Dual-amplitude Pulse Interval Modulation,FDAPIM)等。
单维调制和二维调制都可以基于高阶调制来提高频带利用率,但带来的问题是随着调制阶数的提高,星座点在欧式空间上的欧式距离减少,因此产生判决误差的概率增加。因为为了保证高阶调制的BER性能,不仅要求***工作在高SNR场景,并且解调端需要根据发送端发送的导频信号来确定参考星座点,否则会发生解调性能差,这就需要发送端发送能够携带所有星座点的导频参考信号。因此传统基于高阶调制来提高频谱效率的方式对***开销、功耗和实现复杂度都有较高的要求。而脉冲类调制,包括脉冲位置调制和脉冲间隔调制存在频带利用率不高的缺点。另外传统的调制很少关注于传输可靠性,导致***对噪声、信道衰减、干扰敏感。
因此,如何基于调制获得较高频带利用率或可靠性的同时,能够降低***SNR的要求,同时简化收发端的实现复杂度是本申请需要解决的技术问题。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的调制方法、装置及通信设备进行详细地说明。

步骤1000、第一设备对比特信息进行调制,得到第一符号,其中,所述比特信息中的第一部分比特信息被映射为符号,所述比特信息中的第二部分比特信息被映射为所述符号的位置或间隔。
可以理解的是,第一设备为调制端,可以是终端设备或网络侧设备。
可选地,所述第二部分比特信息为所述比特信息中除了所述第一部分比特信息以外的其他比特信息,即第一部分比特信息和第二部分比特信息组成该比特信息。
例如,比特信息为m+n位比特信息,第一部分比特信息为m为比特信息,第二部分比特信息为n位比特信息,第一设备将m位比特信息映射为符号,将n为比特信息调制到第一部分比特信息映射的符号的位置或符号的间隔维度上。
第一符号可以称为混合调制符号。
在本申请实施例中,通过将比特信息中的第一部分比特信息映射为符号,将比特信息中的第二部分比特信息调制到符号的位置或符号的间隔维度上,可以有效提升频带利用率,且实现简单。
可选地,将第一部分比特信息调制成符号的方式包括以下之一:多载波调制;单载波调制;单维调制;二维调制;绝对调制;相对调制;差分调制。
可选地,所述符号的位置为所述符号在第一时间单元内的位置或位置的排列组合;所述符号的间隔为两个符号之间的第二时间单元的个数。
符号的位置可以理解为该符号在第一时间单元内的第p(1≤p≤P)个第二时间单元的位置。
符号的位置的排列组合,可以理解为在第一时间单元内存在k(2≤k≤P)个符号,这k个符号的相对位置排列组合。
可选地,所述第一时间单元为所述第二时间单元的整数倍。即P(P≥2)个第二时间单元构成一个第一时间单元。例如,第一时间单元的长度为8个时隙,第二时间单元的长度为1个时隙,所述第一时间单元的长度为所述第二时间单元长度的8倍。
可选地,所述第一时间单元的长度相对第二时间单元的长度的倍数是固定或非固定的。
第一时间单元的长度相对于第二时间单元的长度的倍数,可以是固定的,也可以不是固定的,可选地,所述第一时间单元的长度相对第二时间单元的长度的倍数是固定或非固定的,取决于第一设备所采用的调制方式。
在本申请实施例中,所述第一时间单元的长度相对第二时间单元的长度的倍数是固定或非固定的,可以提高传输的灵活性和效率。

符号之间的间隔,即两个符号之间的第二时间单元的数目Q,如果不存在保护时隙,则Q≥0;如果存在保护时隙,则Q≥1。
可选地,所述第一符号的长度为所述第一时间单元的长度。
由于第一部分比特信息被映射成符号,第二部分比特信息被映射成符号的位置或符号的间隔,因此,第一符号的长度等于第一时间单元的长度。
可选地,所述第一部分比特信息和所述第二部分比特信息为不同的比特信息;或者,所述第一部分比特信息和所述第二部分比特信息为相同的比特信息。
在一些可选的实施例中,所述第一部分比特信息和所述第二部分比特信息为不同的比特信息,则说明比特信息的调制模式为复用模式,第一符号携带两部分不同的比特信息,可以获得较高的频带利用率。
下面通过几个具体的实施例对本申请提供的基于复用模式的调制方法进行介绍。
本实施例中,以第一部分为比特信息进行差分振幅键控(Differential Amplitude Shift Keying,DASK)调制,第二部分比特信息进行符号间隔或位置,且调制模式为复用模式,即第一部分比特信息和第二部分比特信息为不同的比特信息为例来解释本申请方案。在本实施例中,由于第一部分的调制符号为映射的脉冲,因此下面以脉冲位置或间隔表示符号位置或间隔,二者在本实施例中具有相同的含义。
一种可实现的方案中,以表征脉冲符号的时隙数固定,且每个脉冲符号时隙内只有单个脉冲,这一类的脉冲调制主要是以PPM调制为主。以2DASK+8PPM联合调制形成的16-DAPM(差分位置-幅度调制(Differential Amplitude Position Modulation,DAPM))为例,图11为本申请实施例提供的2DASK+8PPM联合调制形成的16-DAPM示意图。每个脉冲在一个符号周期内有8种可能的时隙位置,每个脉冲有两种可能的幅度1和α,因此每个脉冲可以携带4比特信息。比如以第一个符号周期为例,该符号周期中的第5个时隙位置上有幅度为1的脉冲,并且该符号周期的上一个脉冲的幅度值为1,因此表征比特信息“0100”,其中第一个比特“0”表示2DASK中的幅度值为1,对应的差分幅度系数为1;剩下的三个比特信息为“100”表示脉冲为符号周期中的第五个时隙位置。值得注意的是,同样以第一个符号周期为例,即该符号周期中的第5个时隙位置上有幅度为1的脉冲,但如果该符号周期的上一个脉冲的幅度值为α,因此表征比特信息“1100”,其中第一个比特“1”表示2DASK中的幅度值为1,对应的差分幅度系数为1/α;剩下的三个比特信息为“100”表示脉冲为符号周期中的第五个时隙位置。
另外一种可实现的方案中,以表征脉冲符号周期的时隙数非固定,且每个脉冲符号时隙内只有单个脉冲,这一类的脉冲调制主要是以DPPM调制、DPIM以及他们的变种DDPPM为主。以2DASK+4DPIM(有保护时隙)联合调制形成的8-DAPM为例,图12为本申请实施例提供的2DASK+4DPIM(有保护时隙)联合调制形成的8-DAPM示意图。每个脉冲符号周期的时隙数不是固定的,DPIM符号由起始时隙脉冲和其后附件的若干个空时隙表示,空时隙的个数根据二进制信源对应的十进制数据来判定,另外为了尽可能降低数据传输过程中码间干扰的影响,在每个DPIM符号后面加上一个保护时隙,这样最小和最大符号长度分别为2Ts和5Ts;另外每个脉冲有两种可能的幅度1和α,因此每个脉冲符号周期可以携带3比特信息。以图中的第二个符号周期为例,该符号周期中的比特信息“101”中的后面两个比特“01”表示该符号周期有三个时隙,其中一个为保护时隙,第一个时隙为脉冲,第二个时隙没有脉冲;“101”比特信息中的第一个比特“1”表示该幅度值为α(上一个符号周期为1)。具体的调制过程可以参考前面的方案,这里不再赘述。
另外一种可实现的方案中,以表征脉冲符号周期的时隙数非固定,且每个脉冲符号时隙内只有多个(大于等于2)脉冲,这一类的脉冲调制主要是以双头脉冲间隔调制(Double-headed pulse interval modulation,DHPIM)等。其中DHPIM调制中的每个符号由头部时隙与后续的空时隙组成。头部时隙固定长度为(β+1)个时隙(β为正整数),分两种情况:β/2个时隙和(β/2+1)个时隙;β个时隙和1个时隙。l为十进制数据对应的十进制数,当1<2L-1,头部时隙组成为前一种情况,后续的空时隙个数为l;当l≥2L-1时,头部时隙组合为后一种情况,后续的空时隙的个数为(2L-1-1-l)。图13为本申请实施例提供的2DASK+16DHPIM联合调制形成的32DAPM示意图。具体的关于2DASK与16DHPIM的调制和解调过程可以参考前述过程,这里不再赘述。
在上述实施例中,基于DASK调制来实现第一部分比特信息的调制,基于时隙固定或非固定的脉冲位置或脉冲间隔调制来实现第二部分比特信息的调制,从而能够获得高频带利用率。容易理解的是,除了DASK,上述实施例方案很容易扩展到第一部分基于QAM,APSK,ASK,PSK,FSK、正交频分复用(Orthogonal Frequency Division Multiple,OFDM)、正交时频空(Orthogonal Time Frequency Space,OTFS)、差分相移键控(Differential phase-shift keying,DPSK)等其它调制。复用模式下的混合调制适用于高速率传输场景或者高SNR通信场景。
在本申请实施例中,所述第一部分比特信息和所述第二部分比特信息为不同的比特信息,通过将第一部分比特信息映射为符号,将第二部分比特信息映射为所述符号的位置或间隔,可以提高频带利用率。
所述第一部分比特信息和所述第二部分比特信息为相同的比特信息,则说明比特信息的调制模式为分集模式,即第一符号携带两部分相同的比特信息,提供了冗余性,可以获得分集增益,提高了传输可靠性。
调制模式为分集模式,即要求第一部分的m位比特信息与第二部分的n位比特相同,即{c0,c1,...,cm}={c0,c1,...,cn}且m=n。调制的时候,可以将m位的比特信息分别映射到调制符号上,同时将相同的n位比特信息映射到已调制符号的位置或间隔维度上,实现分集模式下的混合调制。接收端根据指示分别在符号的位置或符号的间隔维度,以及形成调制符号的维度上进行解调,将得到的两部分的m位比特信息进行加权合并或其它处理(判决或选择合并、最大比合并等),最后得到解调的m位比特信息。
分集模式下混合调制虽然不能提高***的频带利用率,但是可以提高***的传输可靠性,使***获得分集增益,适用于传输可靠性要求高或低SNR通信场景。
在本申请实施例中,所述第一部分比特信息和所述第二部分比特信息为相同的比特信息,通过将第一部分比特信息映射为符号,将第二部分比特信息映射为所述符号的位置或间隔,可以提高***的传输可靠性,使***获得分集增益。
