  • Figure 4 shows the modulation diagram of 8-PPM.
  • Each frame is divided into 8 Time slots, pulse signals are only sent on one time slot within a frame at a time, and the amplitudes of these pulses are the same. Modulation is achieved by changing the relative positions of these pulses on the time slots within the frame to carry information bits. As shown in Figure 4, in the first frame, the pulse is sent on the 5th time slot, then the pulse can carry bit "100"; in the second frame, the pulse is sent on the 2nd time slot, then the pulse can Carrying bit "001".
  • MPPM Multiple Pulse Position Modulation
  • Multi-pulse position modulation MPPM is one of the optimized modulation methods of PPM modulation and has higher frequency band utilization. Unlike PPM modulation, which only sends one pulse in one time slot of each frame, MPPM 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. , but the amplitude and width of each pulse in the sequence remain unchanged.

Different pulse signals, and changing the relative position arrangement and combination of the two pulses on the time slot within the frame 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
  • Multi-pulse position-amplitude 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 modulation diagram of a fourth-order PAM-(8,2)-MPPM. The amplitude of the pulse on the time slot is one of four amplitudes. Therefore, compared with Figure 5, these two pulses can An additional 4 bits are added to MPPM, so 8.8 bits can be carried in one frame.
  • Differential pulse position modulation DPPM is an improved PPM modulation method, which retains the low level before a single pulse and removes the low level after a single pulse on the basis of PPM.
  • Figure 7 is a schematic diagram of a 4DPPM modulation. 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.

反向散射通信(Backscatter Communication，BSC)是指反向散射通信设备利用其它设备或者环境中的射频信号进行信号调制来传输自己信息，是一种比较典型的无源物联设备。反向散射通信发送端的基本构成模块及主要功能包括：
-天线单元：用于接收射频信号、控制命令，同时用于发送调制的反向散射信号。
-能量采集模块或供能模块：该模块用于反向散射通信设备进行射频能量采集，或者其它能量采集，包括但不限于太阳能、动能、机械能、热能等。另外除了包括能量采集模块，也可能包括电池供能模块，此时反向散射通信设备为半无源设备。能量采集模块或供能模块给设备中的其它所有模块进行供电。
-微控制器：包括控制基带信号处理、储能或数据调度状态、开关切换、***同步等。
-信号接收模块：用于解调反向散射通信接收端或是其它网络节点发送的控制命令或数据等。
-信道编码和调制模块：在控制器的控制下进行信道编码和信号调制，并通过选择开关在控制器的控制下通过选择不同的负载阻抗来实现调制。
-存储器或传感模块：用于存储设备的标识(Identification，ID)信息、位置信息或是传感数据等。
除了上述典型的构成模块之外，未来的反向散射通信发送端还可以集成隧道二极管放大器模块、低噪声放大器模块等，用于提升发送端的接收灵敏度和发送功率。
可选的，反向散射通信接收端的基本构成模块及主要功能包括：
-天线单元：用于接收调制的反向散射信号。
-反向散射信号检波模块：用于对反向散射通信发送端发送的反向散射信号进行检波，包括但不限于幅移键控(Amplitude Shift Keying，ASK)检波、相移键控(Phase-Shift Keying，PSK)检波、频移键控(Frequency-Shift Keying，FSK)检波或正交振幅调制(Quadrature Amplitude Modulation，QAM)检波等。
-解调和解码模块：对检波出的信号进行解调制和解码，以恢复出原始信息流。
反向散射通信设备通过调节其内部阻抗来控制调制电路的反射系数Γ，从而改变入射信号的幅度、频率、相位等，实现信号的调制。其中信号的反射系数可表征为：
其中，Z0为天线特性阻抗，Z1是负载阻抗，j表示复数，θT表示相位。假设入射信号为Sin(t)，则输出信号为因此，通过合理的控制反射系数可实现对应的幅度调制、频率调制或相位调制。基于此，反向散射通信设备，可以是传统射频识别 标识(Radio Frequency Identification，RFID)中的标签(Tag)，或者是无源或半无源物联网(Passive/Semi-passive Internet of Things，IoT)。为了方便，这里统称为BSC设备。
图2A示出了本申请实施例可应用的一种单基地反向散射通信***(Monostatic Backscatter Communication System，MBCSs)的示意图。MBCS***包括BSC发送设备(比如标签Tag)和读写器Reader，读写器Reader中包含RF射频源和BSC接收设备，RF射频源用于产生RF射频信号从而来给BSC发送设备/Tag供能。BSC发送设备反向散射经过调制后的RF射频信号，Reader中的BSC接收设备接收到该反向散射信号后进行信号解调。由于从BSC发送设备发送出去的RF射频信号会经过往返信号的信号衰减引起的双倍远近效应，因而信号的能量衰减大，因而MBCS***一般用于短距离的反向散射通信，比如传统的RFID应用。
图2B示出了本申请实施例可应用的一种双基地反向散射通信***(Bistatic Backscatter Communication Systems，BBCSs)的示意图。不同于单基地反向散射通信***(Monostatic Backscatter Communication System，MBCSs)，BBCS***中的RF射频源、BSC发送设备和BSC接收设备是分开的，故可以避免往返信号衰减大的问题。另外，通过合理的放置RF射频源的位置可以进一步提高BBCS通信***的性能。值得注意的是，环境反向散射通信***ABCSs也是双基地反向散射通信***的一种，但与BBCS***中的射频源为专用的信号射频源不同，ABCS***中的射频源可以是可用的环境中的射频源，比如：电视塔、蜂窝基站、WiFi信号、蓝牙信号等。
本申请实施例适用的场景包括但不限于反向散射通信等。
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。下面以几种比较典型的脉冲类位置调制为例进行说明。
1)脉冲幅度调制(Pulse Amplitude Modulation，PAM)
脉冲幅度调制PAM是一种脉冲载波的幅度随基带信号变化的调制方式。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3A所示为2阶PAM的调制示意图，其中用高电平表示“1”，用低电平表示“0”，该调制方式也可以称为开关键控(On-off Keying，OOK)或二进制振幅键控(Amplitude Shift Keying，ASK)。如图3B所示为4阶PAM的调制示意图，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。
2)脉冲位置调制(Pulse Position Modulation，PPM)
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的调制示意图，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，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。如图4所示，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”。
3)多脉冲位置调制(Multiple Pulse Position Modulation，MPPM)
多脉冲位置调制MPPM是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调制中的只在每一帧的一个时隙上发送一个脉冲，MPPM通过调制信号脉冲序列中多个脉冲的相对位置(即相位)，使该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所示为一种2脉冲8-PPM的调制示意图，可记为(8,2)-MPPM，每一帧内分成8个时隙，每次同一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在一帧内传输3比特。因此，MPPM能够实现更高频带利用率的数据传输。
4)多脉冲位置-幅度调制(Multiple Pulse Amplitude Position Modulation，MPAPM)
多脉冲位置-幅度调制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所示为一种4阶PAM-(8,2)-MPPM的调制示意图，时隙上脉冲的幅度为四种幅度中的一种，因此相比于图5，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。
5)差分脉冲位置调制(Differential Pulse Position Modulation，DPPM)
差分脉冲位置调制DPPM是一种改进的PPM调制方式，其在PPM的基础上保留单个脉冲之前的低电平和去掉单个脉冲之后的低电平，如图7所示为一种4DPPM调制示意图。因此相比于PPM，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。
需指出的，在脉冲位置调制PPM中，除了上述提到的MPPM、MPAPM、DPPM之外，还有其它的很多变种，包括但不限于：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。
上述提到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取代脉冲的绝对位置来加载信息也是另外一种选择，如数字脉冲间隔调制(Digital Pulse Interval Modulation，DPIM)。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。此外，为了尽可能降低数据传输过程中码间干扰的影响，可在每个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。如图8A所示为一种无保护时隙下的4DPIM的调制示意图，如图8B所示为一种有保护时隙下的4DPIM的调制示意图。
除了上述单脉冲的DPIM调制之外，还有很多DPIM调制的变种，包括但不限于：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。
为了解决如何在实现高阶调制提升频谱效率的同时，简化信号处理过程的问题，本申请实施例中提出了差分幅度调制(Differential Amplitude Shift Keying，DASK)和脉冲调制的联合调制，此联合调制可称为差分幅度脉冲调制(Differential Amplitude Pulse Modulation，DAPM)，并通过设计调制和解调方法、信令流程、配置参数等，使得通信***能够灵活的实现差分幅度调制和脉冲调制的联合调制和解调制。基于此联合调制，可在保证高功率效率的同时提高频谱效率，且由于采用了差分幅度调制和脉冲调制(比如脉冲位置/间隔调制)，使得发送端不需要发送导频且接收端不需要进行信道估计和信道均衡的情况下完成信号解调，从而可以简化信号处理过程。
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信息处理方法、装置、通信设备及可读存储介质进行详细地说明。
请参见图9，图9是本申请实施例提供的一种信息处理方法的流程图，该方法应用于第一设备，该第一设备为通信***中的发送端/调制端，可选为终端、网络侧设备或BSC***中的BSC发送设备，该BSC发送设备包括但不限于标签Tag、无源或半无源的物联网IoT设备等。如图9所示，该方法包括如下步骤：

一些实施例中，所述第一调制可称为差分幅度脉冲调制(Differential Amplitude Pulse Modulation，DAPM)。
本申请实施例的信息处理方法，第一设备可以确定第一调制的调制参数，所述第一调制为差分幅度调制和脉冲调制的联合调制，并根据该调制参数，对第一信息进行第一调制，获得并发送第一信号。由此，借助差分幅度调制和脉冲调制的联合调制，可以在保证高功率效率的同时提升频谱效率，且由于采用了差分幅度调制，可以使得通信***具有更好的抗信道多径、信号干扰的影响，从而使得发送端不需要发送导频且接收端不需要进行信道估计和信道均衡的情况下完成信号解调，从而简化信号处理过程。
可选的，上述对第一信息进行第一调制的过程可以包括：
第一设备根据所述调制参数，对第一信息中的比特信息进行串并转化，获得第一比特信息和第二比特信息，并根据第一比特信息映射得到第一时刻的幅度差分系数，根据第二比特信息映射得到第一时刻的脉冲调制符号；其中，所述第一比特信息为差分幅度调制比特信息，在根据第一比特信息映射得到第一时刻的幅度差分系数时，可以基于预设的差分幅度调制比特信息与幅度差分系数的对应关系映射得到；所述第二比特信息为脉冲符号调制比特信息，在根据第二比特信息映射得到第一时刻的脉冲调制符号，可以基于预设的脉冲符号调制比特信息与脉冲调制符号的对应关系映射得到；所述串并转化为将串行比特信息转化为并行比特信息，即将第一信息中的比特信息转化为第一比特信息和第二比特信息；
第一设备根据第一时刻的幅度差分系数和第二时刻的脉冲幅度，确定第一时刻的脉冲幅度，所述第二时刻为第一时刻的上一个时刻，所述第一时刻和所述第二时刻为存在脉冲调制符号的时刻；比如，第一时刻为当前时刻t，第二时刻为上一个时刻t-1；
第一设备根据第一时刻的脉冲幅度和第一时刻的脉冲调制符号，确定第一时刻的调制符号，所述调制符号为差分幅度和脉冲联合调制后的符号。
这样，可以基于幅度映射和脉冲映射过程，可以实现对第一信息的差分幅度调制和脉冲调制的联合调制。
一些实施例中，在根据第一时刻的幅度差分系数和第二时刻的脉冲幅度，确定第一时刻的脉冲幅度时，可以将第一时刻的幅度差分系数和第二时刻的脉冲幅度相乘，获得第一时刻的脉冲幅度。
一些实施例中，在根据第一时刻的脉冲幅度和第一时刻的脉冲调制符号，确定第一时刻的调制符号时，可以将第一时刻的脉冲幅度和第一时刻的脉冲调制符号相乘，获得第一时刻的调制符号，即获得差分幅度和脉冲联合调制后的符号。
可选的，上述脉冲调制可以为单幅度脉冲调制或恒幅度脉冲调制。
可选的，上述脉冲调制可以包括以下至少一项：
单脉冲调制或多脉冲调制；
脉冲间隔调制、脉冲位置调制和/或差分脉冲间隔调制；
固定时隙脉冲调制或非固定时隙脉冲调制。
本申请实施例中，第一调制即DAPM为差分幅度调制和脉冲调制的联合调制，对于对DAPM中的每个脉冲进行差分幅度调制，可使得脉冲的幅度信息也可以携带比特信息。
DAPM在空间中映射的集合表达式可以如下所示：
上述式中，Na表示幅度调制的状态数量或者阶数，ma表示幅度调制所需的比特数。Np表示相位脉冲的状态(比如脉冲位置或脉冲间隔)数量，mp表示脉冲调制所需的比特数。M＝Na·Np表示DAPM调制的所有状态的数量，m＝ma+mp表示DAPM调制所需的比特数。α表示DAPSK调制中的幅度分割因子。
DAPM调制中的幅度分割因子α可以是根据调制类型、调制的状态数M和信道状态来确定的，并且可以由α确定DAPM调制的幅度值。表1给出了一种α值在不同调制类型、调制阶数、信道状态下的取值示例。
表1
上述表1中，Rayleigh为瑞利分布，上述Rician为莱斯分布。
一种可能的实现方案中，M-DAPM调制可以分成两个步骤实现：首先根据ma位的比特流映射得到当前时刻(如时刻k)的幅度差分系数γk，并将mp位的比特流映射得到当前时刻的脉冲调制(比如脉冲间隔、位置等调制)符号pk；然后将得到的幅度差分系数γk与上一个时刻(如时刻k-1)脉冲的幅度ak-1相乘，得到当前时刻脉冲的幅度ak，之后与当 前时刻的脉冲调制符号pk相乘，得到当前时刻调制后的符号sk，如图10所示。
如图10所示，具体的调制流程可包括：m位输入比特流经过串并转化之后，形成ma位的差分幅度调制比特流和mp位的脉冲符号调制比特流，然后将ma位的差分幅度调制比特流经幅度映射后生成当前时刻的幅度差分系数γk，和将mp位的脉冲符号调制比特流经脉冲位置/间隔映射后生成当前时刻的脉冲调制符号pk；之后，将幅度差分系数γk与上一个时刻脉冲的幅度ak-1(此由上一个时刻的调制符号sk-1经取模得到)相乘，得到当前时刻脉冲的幅度ak，并将ak与pk相乘，得到当前时刻调制后的符号sk，如下所示：
sk＝ak·pk＝γk·ak-1·pk
其中，当前时刻脉冲的幅度为：ak＝γk·ak-1。
以16-DAPM为例，并且调制类型是由2DASK调制和8DPIM调制联合实现，此可扩展到其它的调制类型和组合方式，对此不作限定。8DPIM调制采用现有的8DPIM调制方式进行调制即可，包括有保护时隙或无保护时隙两种，这里不做过多的介绍。以2DASK调制的幅度分割因子α＝2为例，结合8DPIM调制，DAPM的调制幅度值最大值不超过2。由于幅度2DASK调制过程是将幅度差分系数γk与前一个时刻的幅度调制值ak-1相乘得到当前时刻的幅度调制值ak，因此幅度调制比特与γk的对应关系可如下表2所示。当输入的幅度比特为1，前一个时刻的幅度调制值ak-1＝1时，则当前时刻的幅度调制值ak＝γk·ak-1＝1×α＝2，表示幅度由低电平幅度调制到高电平幅度。当前一个时刻的幅度调制值ak-1＝2，当前的输入比特为1时，则当前时刻的幅度调制值ak＝γk·ak-1＝α×1/α＝1，表示幅度由高电平幅度调制到低电平幅度，以此来保持高低电平幅度之间的相互转换。
表2
以32-DAPM为例，并且调制类型是由4DASK调制和8-MPPM调制联合实现。其中，8-MPPM为2-pulse和8-PPM调制，可记为(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。具体的关于8-MPPM可采用已有的方式进行，这里不做过多的介绍。对于4DASK调制，调制的输入比特与幅度差分系数的映射表可如下表3所示。
表3

以16-DAPM为例，并且调制类型是由4DASK调制和4-DPPM调制联合实现。其中，4-DPPM调制中保留单个脉冲之前的低电平，去掉单个脉冲之后的低电平，因此表征一个4-DPPM的符号的时隙数是不固定的。其具体的调制原理可以参考已有技术，这里不做过多的介绍。而对于4DASK，可采用上述表3所示的映射表。
DAPM的解调过程是调制的逆过程，需要对脉冲幅度进行解差分，并且对脉冲的位置/间隔进行解调制。如图11A所示，接收端接收到信号rk(t)后，分别同时进行脉冲幅度和脉冲位置/间隔解调，DASK解调会逆映射出ma位比特流(即比特信息)，脉冲位置/间隔解调会逆映射出mp位比特流；之后，ma位比特流和mp位比特流经并串转化后合成输出比特流。其中rk(t)可以表示为：
上式中，ρk为脉冲的幅度；cl∈{c0,c1,...,cL-1}为映射后的时隙序列，其值为0或者1；p(t)为幅值为1、宽度为的矩形脉冲；T为周期。对于不同的调制类型，L有可能不是固定的，具体的和每种脉冲调制类型相关。
以16-DAPM解调制为例，并且以调制类型是由2DASK调制和8DPIM调制联合实现，此可扩展到其它的调制类型和组合方式；解调端为2DASK解调和8DAPSK解调。2DASK解调过程如图11B所示，接收信号rk(t)经过脉冲取模运算，得到rk(t)的幅度值ρk，将幅度值ρk延时一个周期T的时间后，再与幅度值ρk做除法(此类似于对ρk取倒数)，除法的结果会得到一个值，利用判决门限，就可解调恢复出ma位比特流。过程如下：
其中，|·|表示取模运算。得到之后需要经过判决门限后，才能解调恢复出ma位比特流，其中判决门限取值可如下：
当M＝16时，根据调制过程中所定义的幅度分割因子来确定解调门限，比如根据调制编码过程中所定义的α＝2，可知有：
至于8DPIM的解调过程可以采用现有的技术，这里不做过多的介绍。
类似的，对于由4DASK调制和8-MPPM调制联合实现的32-DAPM解调为例，其中 的4DASK的解调过程及对应阈值如下表4所示：
表4
下面结合具体实施例对本申请中的第一调制即DAPM进行说明。
实施例一：固定时隙数+单脉冲
由于脉冲幅度/间隔调制方式的多样性，因此使得DAPM的调制种类同样多样性。本实施例一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为例，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。比如图12所示，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,对应的幅度差分系数为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，对应的幅度差分系数为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。其他符号周期中的脉冲表征比特信息的方式与第一个符号周期中的脉冲表征比特信息的方式相同，在此不再赘述。
实施例二：固定时隙数+多脉冲
本实施例二以表征脉冲符号的时隙数固定，且每个脉冲符号时隙内有两个或两个以上的脉冲，这一类的脉冲调制主要是以MPPM调制、双脉冲间隔调制(Dual Pulse Pulse Interval Modulation，DPPIM)等为主。以4DASK+8MPPM联合调制形成的32-DAPM为例，每个脉冲符号周期有8个时隙位置，每个符号周期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符号周期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另外每个脉冲有4中可能的幅度值1,α,α2,α3；因此每个符号周期内可能携带2+log228＝6.8个比特。其中每个脉冲的幅度信息携带2比特信息，一个符号周期内的脉冲的相对位置组合携带4.8比特信息，具体的脉冲调制形式可如图13所示，具体的调制方式与上述实施例类似，这里不再赘述。
实施例三：非固定时隙数+单脉冲
本实施例三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、DPIM以及相应变种DDPPM为主。以2DASK+4DPIM(有保护时隙)联合调制形成的8-DAPM为例，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。比如图14所示，以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”表示脉冲幅度值为α(上一个符号周期的脉冲幅度值为1)。具体的调制过程可以参考前面的方案，这里不再赘述。
实施例四：非固定时隙数+多脉冲
本实施例四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有多个(大于或等于2)脉冲，这一类的脉冲调制主要包含双头脉冲间隔调制(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l＜2L-1时，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)。以2DASK+16DHPIM(β＝1，2)组成的32DAPM为例，具体的脉冲调制形式可如图15所示。具体的关于2DASK与16DPIM的调制和解调过程可以参考前述过程，这里不再赘述。
