Description
本申请要求在2017年4月13日提交中国专利局、申请号为201710239038.8、发明名称为“一种有源阵列天线的信号处理方法和装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本发明涉及通信技术领域,尤其涉及一种有源阵列天线的信号处理方法和装置。
从20世纪80年代起,天线理论和技术发生了巨大的变化,其中一个重要的部分就是有源天线,特别是有源阵列天线的深入研究和广泛使用。
由有源电路与天线阵列中的每一个辐射单元或子阵通道直接连接而组成的接收或发射电磁波的***即为有源阵列天线,每个有源单元除了作为辐射/接收单元,辐射/接收电磁信号之外,还作为电路的一部分,具有谐振、滤波、功率放大等作用。有源阵列天线是今后天线阵列设计发展的一个重要趋势,是后续天线***小型化,智能覆盖,绿色基站的重要发展方向。
有源阵列天线具有较为优异的性能。如很容易对信号进行处理从而进行各种波束赋形,并可以实时调整,具有快速识别覆盖目标和自适应抗干扰的能力。有源阵列消除了馈线***的损耗,大大提高了发射机功率的有效性。在有源单元出现故障后,具备自适应调整的能力,仍然保持良好覆盖;并且通过节能降低了有源器件的温度,提高了有源器件的可靠性。因此,有源阵列天线在雷达、通信、电子对抗***中有着广泛的应用前景。

图3示例性示出了本发明实施例提供的一种有源阵列天线的信号处理方法的流程示意图,如图3所示,从阵列控制模块侧来说,本发明实施例提供的信号处理方法,包括以下步骤:
步骤301、阵列控制模块确定核心网方向传来的第一基带数据所属的波束以及所述第一基带数据对应的发送/接收T/R模块;其中,一个T/R模块包括 多个天线振子;
步骤302、所述阵列控制模块从所述第一基带数据中确定出待合并的第一基带数据,所述待合并的第一基带数据属于同一波束且对应于同一T/R模块的同一时刻的第一基带数据;
步骤303、所述阵列控制模块将所述待合并的第一基带数据进行合并;
步骤304、所述阵列控制模块将合并后的第一基带数据发送给相应的T/R模块,以使所述T/R模块将所述合并后的第一基带数据处理为第一射频信号后通过多个天线振子向外发射。
本发明实施例中,有源阵列天线中包括阵列控制模块和T/R模块,其中,一个T/R模块包括多个天线振子。阵列控制模块接收核心网方向发送的第一基带数据后,确定第一基带数据所属的波束以及第一基带数据对应的T/R模块,然后,将属于同一波束且对应于同一T/R模块的同一时刻的第一基带数据作为待合并的第一基带数据。阵列控制模块将待合并的第一基带数据进行合并,并将合并后的第一基带数据发送给相应的T/R模块,这样可以有效降低第一基带数据传输时占用的传输资源。T/R模块接收到合并后的第一基带数据后,将所述合并后的第一基带数据处理为第一射频信号并通过多个天线振子向外发射。现有技术中,阵列控制模块需根据天线振子的数量设置连接线路,即一个天线振子对应一条线路,由于天线振子的数量越来越多,则对应的链路也越来越多,故有源阵列天线中的线路连接较为复杂。本发明实施例中,阵列控制模块连接多个T/R模块,且一个T/R模块中包括多个天线振子,这样,阵列控制模块只需针对一个T/R模块设置一条链路,即可发送针对多个天线振子的数据,因此,减少了链路的数量,降低了有源阵列天线的结构复杂度,减小了天线装置的体积。
阵列控制模块将合并后的第一基带数据发送给相应的T/R模块之后,T/R模块将接收到的第一基带数据处理后通过天线振子向外发射,包括:

所述T/R模块将每个天线振子的第一基带数据处理为第一射频信号,并将第一射频信号通过对应的天线振子向外发射。
T/R模块接收到合并后的第一基带数据后,首先将合并后的第一基带数据分开,分成对应于每个天线振子的第一基带数据,然后对每个第一基带数据波束赋形。波束赋形是应用传感器阵列实现定向信号发送或接收的信号处理技术。波束赋形技术能够在某个特定角度(目标用户)增强信号,在另一个特定角度(非目标用户,或者障碍物)减弱信号。波束赋形能够同时在发送端和接收端实现空间的选择性。相比具有全向接收/发送天线的改善被称为接收/发射增益(或损失)。
T/R模块将波束赋形后的基带信号转换成中频信号,然后再转换为射频信号发射出去。中频,顾名思义,是指一种中间频率的信号形式。中频信号是相对于基带信号和射频信号来讲的,中频可以有一级或多级,它是基带和射频之间过渡的桥梁。射频信号就是高频信号,就是我们所说的电磁波,可以向空间辐射。因为有些信号本身可能不太适合直接发射出去(频率非法,或信号本身条件不允许)。所以要将信号调制,调制器本身需要一个适合的震荡信号,将原信号加在上面,这个震荡信号叫载波,调制后的载波就包含了原信号的信息,发射出去就叫电波。所以,射频信号就是经过调制的,拥有一定发射频率的电波。
本发明实施例中,阵列控制模块发送到T/R模块的基带数据包括数据信号和控制信号,若某一时刻,阵列控制模块向N个T/R模块发送A
1个基带数据,其中,第i个T/R模块接收M
i路数据,每路数据包含P
ij个载波(1≤i≤N,1≤j≤M
i),其中一路数据与一个天线振子对应,也就是说该第i个T/R模块向第j个天线振子发送P
ij个数据,若阵列控制模块未将数据进行合并, 则阵列控制模块在该时刻总共发送的数据个数A
1满足下列公式:
本发明实施例中,阵列控制模块将要发送给T/R模块的数据根据不同的T/R模块进行分组,并将同一时刻属于同一波束的数据合并,合并后传输到对应的T/R模块,若每个T/R模块接收X
i路数据,每路数据包含Y
ij个载波,则合并后阵列控制模块总共发送的数据个数A
2满足下列公式:
合并后,阵列控制模块发送给T/R模块的数据的数量小于或等于未合并时阵列控制模块发送给T/R模块的数据的数量,即A
1≥A
2。当A
2个数据到达各个T/R模块后被分开后实施波束赋形,则恢复成A
1个数据。最后,这些数据变为射频后辐射到空中形成各个波束。
特殊地,当阵列控制模块发送给T/R模块的所有数据均属于不同波束,即阵列控制模块不能将数据进行合并,则此时A
1=A
2。
上述步骤303中,阵列控制模块将所述待合并的第一基带数据进行合并,包括:
若所述待合并的第一基带数据均相同,则所述阵列控制模块从所述待合并的第一基带数据中任选一个作为合并后的第一基带数据;
若所述待合并的第一基带数据不同,则所述阵列控制模块将所述待合并的第一基带数据相加得到合并后的第一基带数据。
具体来说,本发明实施例中,将同一时刻属于同一波束的基带数据进行合并后内部传输,该合并并非是并行转换成串行,而是若待合并的数据不同,则将数据相加成一路基带数据,或者若待合并的数据均相同,则只保留一路数据,这样可以降低阵列控制模块与T/R模块之间的传输带宽。需要说明的是,上述基带数据合并的方式仅为举例,不做限制,其它可适用于将基带数 据进行合并的方法均在本发明实施例的保护范围之内。
为了进一步降低传输带宽,本发明实施例中,步骤303与步骤304之间,即所述阵列控制模块将所述待合并的第一基带数据进行合并之后,所述阵列控制模块将合并后的第一基带数据发送给相应的T/R模块之前,还包括:
所述阵列控制模块对所述合并后的第一基带数据进行压缩。
相应的,所述T/R模块接收阵列控制模块发送的合并后的第一基带数据之后,所述T/R模块将所述合并后的第一基带数据分成对应于每个天线振子的第一基带数据之前,还包括:
所述T/R模块对合并后的第一基带数据解压缩。
本发明实施例中将数据进行压缩和解压缩,以减少数据传输所需占用的资源,例如去除LTE信号的循环前缀。任意能将数据进行压缩的方法均适用于本发明实施例,例如DFT(Discrete Fourier Transform,离散傅里叶变换)和IDFT(Inverse Discrete Fourier Transform,离散傅里叶逆变换),阵列控制模块利用DFT将第一基带数据压缩后,T/R模块利用IDFT将压缩后的第一基带数据解压缩。本发明实施例中,数据压缩和解压缩的方法包括但不限于上述这一种方法。
上述过程为从阵列控制模块将基带数据发送给T/R模块的下行传输过程,与下行传输过程相反,在上行传输过程中,是T/R模块将通过天线振子接收到的射频信号转换为基带信号后,发送回阵列控制模块。上行过程包括:
所述T/R模块通过多个天线振子接收多个第二射频信号,并将每个第二射频信号处理为第二基带数据;
所述T/R模块将属于同一波束的同一时刻的第二基带数据进行合并,并将合并后的第二基带数据发送给所述阵列控制模块。
所述阵列控制模块接收T/R模块发送的第二基带数据,所述第二基带数据为所述T/R模块将从多个天线振子接收到的第二射频信号处理后得到的;
所述阵列控制模块将待合并的第二基带数据进行合并,并将合并后的第二基带数据发送给所述核心网方向;所述待合并的第二基带数据属于同一波 束且对应于同一T/R模块的同一时刻的第二基带数据。
上行传输与下行传输为相反的处理过程,在此不做赘述。唯一不同的是,在上行传输过程中,每个T/R模块首先将各自模块内部属于同一个波束的同一时刻的第二基带数据进行合并,每个T/R模块将初次合并后的第二基带数据发送给阵列控制模块后,阵列控制模块再将接收到的各个第二基带数据进行再次合并,将属于同一波束而对应于不同T/R模块的第二基带数据进行合并。
相应于下行传输,在上行传输中,所述T/R模块将属于同一波束的同一时刻的第二基带数据进行合并,包括:
若同一时刻属于同一波束的多个第二基带数据相同,则所述T/R模块从所述多个第二基带数据中任选一个第二基带数据作为合并后的第二基带数据;
若同一时刻属于同一波束的多个第二基带数据不同,则所述T/R模块将所述多个第二基带数据相加得到合并后的第二基带数据。
同样的,数据的传输也经过压缩和解压缩的过程,即所述T/R模块将同一时刻属于同一波束的多个第二基带数据进行合并之后,所述将合并后的第二基带数据发送给所述阵列控制模块之前,还包括:
所述T/R模块对合并后的第二基带数据进行压缩。
所述阵列控制模块接收T/R模块发送的第二基带数据之后,所述阵列控制模块将待合并的第二基带数据进行合并之前,还包括:
所述阵列控制模块对接收到的第二基带数据解压缩。
此外,为了进一步提升有源阵列天线的性能,本发明实施例中还包括:
所述阵列控制模块接收本振信号分发器发送的第一本振信号,所述第一本振信号与所述本振信号分发器发送给T/R模块的第二本振信号相同;
所述阵列控制模块接收工作时钟分发器发送的第一时钟信号,所述第一时钟信号与所述工作时钟分发器发送给T/R模块的第二时钟信号相同。
相应的,从T/R模块侧而言,包括:
所述T/R模块接收本振信号分发器发送的第二本振信号,所述第二本振信号与所述本振信号分发器发送给所述阵列控制模块的第一本振信号相同;
所述T/R模块接收工作时钟分发器发送的第二时钟信号,所述第二时钟信号与所述工作时钟分发器发送给所述阵列控制模块的第一时钟信号相同。
有源阵列天线中进行波束赋形的T/R模块之间的差别,幅度差别与相位差别会影响波束性能。本发明实施例中,如图4所示,本振信号分发器向阵列控制模块以及每个T/R模块发送相同的本振信号,类似的,工作时钟分发器向阵列控制模块以及每个T/R模块发送相同的时钟信号。
具体来说,下行传输过程中,阵列控制模块根据第一本振信号和第一基带数据确定第一校准信号,并向T/R模块发送第一校准信号,以使T/R模块根据所述第一校准信号校准第一射频信号。T/R模块根据接收到的第二本振信号和第一基带数据,确定第一射频信号,再通过天线振子向外发射。同时,T/R模块接收阵列控制模块发送的第一校准信号,并根据第一校准信号校准第一射频信号。在上行传输过程中,T/R模块将通过将多个天线阵子接收到的多个第二射频信号进行耦合,得到第二校准信号,并向阵列控制模块发送第二校准信号,以使阵列控制模块根据第二校准信号校准第二基带数据。同时,T/R模块根据第二本振信号和第二射频信号,确定第二基带数据。
阵列控制模块的校正通道单元的混频电路所需本振信号和T/R模块里面中射频链路的混频电路所需本振信号为相同的本振信号,各个T/R模块之间波束赋形具有相同的本振信号能够降低形成波束赋形时的波束差异,从而提高波束赋形性能。
在此基础上,阵列控制模块的ADC(Analog-to-Digital-Converter)/DAC(Digital-to-Analog-Converter)等电路所需的时钟信号与T/R模块里的ADC/DAC等电路所需的时钟信号,均由同一工作时钟分发器提供,这样能进一步降低阵列控制模块和各个T/R模块之间在形成波束赋形时刻的幅度、相位差异,从而提高整个装置的波束性能。
下面以具体的实施例来说明基带数据合并后,阵列控制模块向T/R模块 传输数据的过程。
实施例1
如图5所示,在有源阵列天线装置中实现8×12的天线阵列。实现过程可以为每个T/R模块含有16个天线振子,每个天线振子1个载波,即每个天线振子均为单载波。
不形成波束的情况:每个T/R模块对应16个天线振子,对应16个载波,若每个通道的数据同一时刻都不在同一波束,则阵列控制模块向每个T/R模块发送16个载波独立的数据。
实施例2
如图6所示,为同一时刻形成两个波束的情况。第一个波束涵盖2个T/R模块,这两个T/R模块中每个T/R模块的4个天线振子在第一个波束,由于每天线振子只有1个载波,故第一个波束对应于8个载波;剩下的T/R模块通道在第二个波束。
在下行传输过程中,阵列控制模块将发送给第1个T/R模块的基带数据进行合并,则第1个T/R模块从阵列控制单元接收2个基带数据,第1个T/R模块接收的第1个基带数据在经过进行波束赋形后变成4个载波数据,对应到4个天线阵子;第1个T/R模块接收的第2个基带数据在经过进行波束赋形后变成12个载波数据,对应到12个天线阵子;上行是下行的逆过程。
第2个T/R模块和第1个T/R模块类似。
第3、4、5、6个模块,都只接收1个基带数据,在T/R模块经过进行波束赋形后变成16个载波数据,对应到各自16个天线阵子。
实施例3
如图7所示,每个T/R模块含有16个天线振子,每个天线振子4个载波。
同一时刻有形成两个波束,第一个波束涵盖2个T/R模块。这两个T/R模块中每个T/R模块中的4个天线振子的2个载波在同一波束;剩下的天线振子的载波在第二个波束。
下行传输过程,第1个T/R模块从阵列控制单元接收2个基带数据,第1 个T/R模块接收的第1个基带数据(2个载波)在经过进行波束赋形后变成8个载波数据(每个天线振子2个载波),对应到4个天线阵子;第1个T/R模块接收的第2个基带数据在经过进行波束赋形后变成56个载波数据,其中上面4个天线振子每个天线振子2个载波,下面12个天线振子每个天线振子4个载波。上行是下行的逆过程。
第2个T/R模块和第1个T/R模块类似。
第3、4、5、6个模块,都只接收1个基带数据,(4个载波)在T/R模块经过进行波束赋形后变成64个载波数据,对应到各自16个天线阵子。
实施例4
如图8所示,形成1个波束。每个T/R模块16个天线振子,每个天线振子4个载波数据,同一时刻都在相同一束波束里面,则每个T/R模块和阵列控制模块之间需要传输1个基带数据。下行数据为阵列控制模块将合并后的基带数据传输到T/R模块,T/R模块解压数据后实施波束赋形,再分为64个载波数据到对应的同一时刻属于同一波束的16个天线阵子;上行数据为T/R模块接收同一时刻属于同一波束的16个天线阵子的数据,实施波束赋形功能之后合并进行数据压缩,再传输到阵列控制模块解压,阵列控制模块对所有数据进行合并。
