目前，发射信号的ACLR指标的调试主要在PA(PowerAmplifier，功率放大器)参数以及PA后端阻抗的调试。PA参数可以是合适的静态偏置电流值，但是静态电流和阻抗的调试往往需要多次尝试不同的值，并且每调试完一次还需要设备校准，而设备校准需要校准环境，从而ACLR指标的调试易受调试环境的限制，而且整个调试过程复杂。

本公开提供的技术方案带来的有益效果至少如下：
本公开提供了一种天线的发射信号的调整方法、装置、系统及介质，与现有技术相比，本公开获取耦合信号之后确定耦合信号的相邻频道泄漏比ACLR，然后将耦合信号的ACLR和预设的目标ACLR进行比较，当耦合信号的ACLR小于预设的目标ACLR时，代表耦合信号的ACLR并不符合要求，对待发射数字信号在相邻信道的信号进行数字滤波，滤除干扰信号，使得待发射数字信号在相邻信道的信号功率降低，从而使得待发射数字信号的ACLR增大。由于耦合信号是收发器内的待发射数字信号对应转换为模拟信号后输出，也就是第一信号经过预定处理后再由耦合器分出的信号，耦合信号的ACLR也相应增大，直到耦合信号的ACLR不小于预设的目标ACLR，说明耦合信号的ACLR的满足要求。
本公开实施例的耦合信号是耦合器将获取的第二信号按预定比例对在信道内的信号和在相邻信道的信号进行功率耦合后得到耦合信号，并将耦合信号从第二信号分出，那么也就是耦合信号的ACLR与第二信号的ACLR相同，第二信号分出耦合信号外的其余信号的ACLR与第二信号的ACLR相同，也就是第三信号的ACLR与第二信号的ACLR相同。当耦合 信号的ACLR的满足要求时，第三信号的ACLR也满足要求，第三信号为天线获取的发射信号，从而使得天线的发出的发射信号满足要求。
本公开是一种闭环的软件调试方法，不需要增加硬件，从而也不需要对设备进行调试，进而不受调试环境限制，采用软件可以进行自动调试，可以循环多次调试直到收发器输出的第一信号的ACLR得到理想的最优值，而且调试过程简单。

本公开实施例提供了一种天线的发射信号的调整方法，可以由带有天线的设备执行，参见图1所示，包括如下步骤：
S101、获取耦合信号，确定耦合信号的相邻频道泄漏比ACLR；耦合信号为收发器输出的第一信号经过预定处理后再由耦合器分出的信号，第 一信号为收发器内的待发射数字信号转换而成的模拟信号，待发射数字信号包括信道内的信号和相邻信道内的信号。
本公开的发明人考虑到，耦合信号是耦合器分出的信号，其余信号是天线会发射出去的信号，其余信号的ACLR与耦合信号的ACLR相同，这样如果耦合信号的ACLR不符合要求，则需要调整进入耦合器输出到天线的信号的ACLR。因此，需要确定耦合信号的ACLR，便于确保天线的发射信号的ACLR能够达到要求。
可选地，步骤S101中，确定耦合信号的相邻频道泄漏比ACLR，包括：测量耦合信号在信道的信号功率和耦合信号在相邻信道的信号功率；将在信道的信号功率和在相邻信道的信号功率相除，得到耦合信号的ACLR。
在实际应用中，耦合信号在信道和该信道的相邻信道的功率可以直接测量得到。
S102、确定耦合信号的ACLR是否小于预设的目标ACLR，当耦合信号的ACLR小于预设的目标ACLR时，执行步骤S103；当耦合信号的ACLR不小于预设的目标ACLR时，执行步骤S104。
S103、对待发射数字信号在相邻信道内的信号进行数字滤波，并将数字滤波后的待发射数字信号作为新的待发射数字信号。
在实际应用中，收发器输出的信号先是数字信号，然后再将滤波后的数字信号转换为模拟信号后输出。本公开在实际应用中可以根据具体情况选用滤波器，比如卡尔曼或者巴特沃斯或者其他过滤器对相邻信道的数字信号进行数字滤波，可以根据实际场景来选择采用何种数字滤波器，实现对数字信号的数字滤波。
S104、对待发射数字信号不进行滤波处理。
可选地，步骤S101中的，预定处理包括以下至少一项处理：功率放大处理、滤波处理、功率耦合处理。
可选地，本公开的调整方法是一个不断循环的过程，每次收到耦合信号进行确定耦合信号的ACLR是否小于预设的目标ACLR，根据确定结果进行步骤S103或步骤S104的处理，可以不断调整耦合信号的ACLR，直 到耦合信号的ACLR不小于预设的目标ACLR，满足信号的要求。天线发射的耦合信号的过程是一个快速迭代过程，是个闭环系统。
在实际应用中，将待发射数字信号由数字信号转换为模拟信号之后得到第一信号，第一信号可以依次经过功率放大、滤波和功率耦合后得到耦合信号。耦合信号可以是耦合器将第二信号在信道内和相邻信道的信号按照预定比例进行功率耦合后得到的信号，第二信号的ACLR和耦合信号的ACLR均与待发射数字信号的ACLR是相同的。耦合信号是第二信号的耦合值，也就是从第二信号的通路提取出一小部分信号，这个耦合值表征了第二信号的特性，也表征了待发射数字信号的特性，类比于待发射数字信号，只是功率值小一些，相当于小功率值的待发射数字信号。
例如：待发射数字信号为20dBm(分贝毫瓦)，耦合信号可能只有0.1dBm。再例如：待发射数字信号在信道的信号功率和在相邻信道的信号功率分别为100dBm和10dBm，这时ACLR为10，如果耦合度为10，则耦合后的信号分别为10dBm和1dBm，也就是耦合后的信号ACLR也为10，也就是耦合信号和待发射数字信号的ACLR是一致的，然后确定耦合后的耦合信号是否满足需要，也就是待发射数字信号是否满足需要，然后根据确定结果调整待发射数字信号的ACLR，进而调整耦合信号的ACLR。
本公开的发明人考虑到，耦合信号的ACLR不符合要求的情况下，则需要调整收发器的待发射数字信号的ACLR，使得天线的发射信号的ACLR符合要求。如果调整与耦合信号对应的待发射数字信号的ACLR，在收发器的待发射数字信号对应转换为模拟信号的第一信号并进行预定处理后，得到的耦合信号的ACLR也会相应调整。由于信号的ACLR是在信道的信号功率和在相邻信道的信号功率相除的结果，那么降低在相邻信道的信号功率就可以增大信号的ACLR。因此，发明人对待发射数字信号在相邻信道的信号进行滤波，滤除干扰信号，降低相邻信道的信号功率，从而增大待发射数字信号ACLR，进而增大耦合信号的ACLR。本公开可以循环确定耦合信号的ACLR，直到耦合信号的ACLR达到预设的目标ACLR，满足信号的要求。
本公开获取耦合信号之后确定耦合信号的相邻频道泄漏比ACLR，然 后将耦合信号的ACLR和预设的目标ACLR进行比较，当耦合信号的ACLR小于预设的目标ACLR时，代表耦合信号的ACLR并不符合要求，对待发射数字信号在相邻信道的信号进行数字滤波，滤除干扰信号，使得待发射数字信号在相邻信道的信号功率降低，从而使得待发射数字信号的ACLR增大。由于耦合信号是收发器内的待发射数字信号对应转换为模拟信号后输出，也就是第一信号经过预定处理后再由耦合器分出的信号，耦合信号的ACLR也相应增大，直到耦合信号的ACLR不小于预设的目标ACLR，说明耦合信号的ACLR的满足要求。
本公开实施例的耦合信号是耦合器将获取的第二信号按预定比例对在信道内的信号和在相邻信道的信号进行功率耦合后得到耦合信号，并将耦合信号从第二信号分出，那么也就是耦合信号的ACLR与第二信号的ACLR相同，第二信号分出耦合信号外的其余信号的ACLR与第二信号的ACLR相同，也就是第三信号的ACLR与第二信号的ACLR相同。当耦合信号的ACLR的满足要求时，第三信号的ACLR也满足要求，第三信号为天线获取的发射信号，从而使得天线的发出的发射信号满足要求。
本公开是一种闭环的软件调试方法，不需要增加硬件，从而也不需要对设备进行调试，进而不受调试环境限制，采用软件可以进行自动调试，可以循环多次调试直到收发器输出的第一信号的ACLR得到理想的最优值，而且调试过程简单。
本公开是获取已经进行预定处理后再由耦合器分出的耦合信号，不是直接检测未经过预定处理的待发射数字信号，检测经过预定处理后的耦合信号的ACLR是否符合要求，也就是耦合器从第二信号中分出耦合信号的其余信号是否达到最优值，其余信号即天线发出的第三信号，对收发器的待发射数字信号的ACLR进行调整，使得检测结果更准确，收发器的待发射数字信号的ACLR进行调整，使得天线能够发射达到预设的理想效果的发射信号，改善输出信号性能指标。

    所述耦合器，用于将获取的第二信号按预定比例在信道内的信号和在相邻信道的信号进行功率耦合后得到耦合信号，并将耦合信号从第二信号中分出后得到第三信号；所述第二信号为收发器输出的第一信号经过预定处理后得到；
    所述天线，用于获取所述第三信号作为发射信号，并将所述发射信号发出。
  8. 根据权利要求7所述的天线的发射信号的调整系统，还包括：电连接的放大器和滤波器，所述放大器与所述收发器电连接，所述滤波器与所述耦合器电连接；
    所述放大器，用于获取所述第一信号，将所述第一信号进行功率放大后得到第四信号；
    所述滤波器，用于获取所述第四信号，对所述第四信号进行滤波后得到所述第二信号。
  9. 根据权利要求8所述的系统，其中，所述收发器还用于测量所述耦合信号在所述信道的信号功率和所述耦合信号在所述相邻信道的信号功率；将在所述信道的信号功率和在所述相邻信道的信号功率相除，得到所述耦合信号的ACLR。
  10. 一种非暂时性计算机可读存储介质，所述非暂时性计算机可读存储介质存储有至少一条指令、至少一段程序、代码集或指令集，所述至少一条指令、所述至少一段程序、所述代码集或指令集由处理器加载并执行以实现权利要求1至3中任一项所述的方法。
