为了使本发明实施例的描述更加清楚，下面结合可选实施例进行描述和说明。
本发明可选实施例提供了一种无线通信设备频谱自检的方法，在本发明可选实施例中以远端射频单元(即RRU)为例进行描述和说明。
为了克服目前在线运营RRU出现故障时，采用更换RRU的方法造成的硬件故障排查的不便，本发明可选实施例提供的无线通信设备频谱自检的方案中，通过下行链路下发内部存储的数据源，然后再通过反馈链路传输并计算处理，可以快速的诊断出整机的故障原因，从而可以提高故障排查的效率，并降低成本。
图6是根据相关技术的RRU的结构示意图；图7是根据本发明可选实施例的RRU的结构示意图，如图7所示，其中，数模转换器(Digital-to-Analog Converter，简称为DAC)、混频器1、滤波器、功放、双工器构成了图3所示的数模处理模块226。图7相对于图6，增加了DSP处理模块、数据存储模块和DSP控制模块。通过增加的这些模块，可以实现频谱检测。
基于图7的RRU，在RRU中增加DSP数据处理模块、数据存储模块、数据传输模块，并在网管系统增加了显示模块后，本发明可选实施例采用下列方案实现基于频谱显示的故障检测：
DSP数据处理模块，完成时域信号变换为频域信号；
数据存储模块，存储射频固定测试模式数据源，在进行检测时可以通过下行链路下发；也存储反馈链路采集的DSP处理后数据，在出现异常时，可以通过调用之前的数据，进行频谱分析；
数据传输模块，传输频谱数据和控制信息；
显示模块，进行频谱显示。
通过上述方案，可以通过检测RRU频谱，实时监控RRU运行状态。在RRU出现故障时，可以通过频谱检测，判定出现问题的模块，从而减少上站检测和更换成本。
下面结合流程图对本发明可选实施例进行描述和说明。
可选实施例一
在本可选实施例中，以频谱检测为例进行说明。图8是根据本发明可选实施例的频谱检测的流程图，如图8所示，该流程包括如下步骤：
步骤S801，通过网管系统(例如：LTE网络管理系统)发起频谱检测命令，可以选择多种检测模式，例如，协议规定的频谱类测试模式：相邻信道功率(Adjacent Channel Power，简称为ACP)、频谱辐射掩模(Spectrum Emission Mask，简称为SEM)等，通过基带部分(Building Baseband Unit，简称为BBU)将命令发送到RRU的中央处理单元(CPU)进行处理；
步骤S802，RRU收到频谱检测命令后，进行数据的采集和处理，包括步骤S8021～步骤S8024：
步骤S8021，FPGA数据模块通过CPU控制模块获取小区的配置信息；
步骤S8022，双工器之后的输出端通过耦合器耦合出一部分输出功率，模拟信号通过混频变换为中频模拟信号；
步骤S8023，将中频模拟信号通过数字中频部分转换为基带信号，其中，数字中频部分的处理包括：数字下变频(Digital Down Converter，简称为DDC)、模数转换(Analog-to-Digital Converter，简称为ADC)和抽取滤波等部分；
步骤S8024，将基带信号通过DSP进行快速傅里叶变换(Fast Fourier Transformation，简称为FFT)，并且将计算得到的基带数据通过数据存储模块进行存储，将数据存储模块中缓存的基带数据按照网管配置的消息将相应的基带数据上传至基带；
步骤S803，基带将基带数据传递给网管系统的操作维护管理(Operation Administration Maintenance，简称为OAM)模块；在网管系统中根据FPGA数据模块获取的配置信息和上述基带数据绘制频谱，并将绘制的频谱显示到后台操作界面。这样就可以从网管系统的后台查看到RRU的频谱图，进而根据频谱图定位RRU故障。
可选实施例二
在本可选实施例中，以误差向量幅度(Error Vector Magnitude，简称为EVM)检测为例进行说明。由于频谱恶化导致信道质量差，进而导致EVM变差，因此，通过EVM检测也可以对无线通信设备进行检测。图9是根据本发明可选实施例的EVM检测的流程图，如图9所示，该流程包括如下步骤：
步骤S901，通过网管系统(例如LTE网络管理系统)发起EVM检测命令，可以选择多种检测模式，例如，ACP、SEM等，通过BBU将命令发送到RRU的CPU进行处理；
步骤S902，RRU收到EVM检测命令后，FPGA数据模块通过CPU控制模块获取小区配置信息；
步骤S903，根据获取到的配置信息从数据存储模块下发与测试模式匹配的数据源，数据源通过下行链路至耦合器端；
步骤S904，通过反馈链路将前向数据采集到ADC处理；
步骤S905，将ADC转换后的数据，送到DSP数据处理模块，进行数据处理；
步骤S906，DSP数据处理模块将计算结果通过CPU和基带接口传输给网管系统(例如LTE网络管理系统)；
步骤S907，网管系统将本次测试结果显示到后台界面，这样就可以从网管后台查看到RRU的各测试模式下的EVM值。
综上所述，通过本发明的上述实施例和可选实施例，通过RRU频谱自检和后台显示的方式，可以实现在线运营RRU的远程故障定位，减少上站检测的成本和时间，降低运营成本；此外，还可以通过检测到的频谱，判定整机是否存在杂散泄露等应硬件问题。
工业实用性：通过上述描述可知，本发明实施例解决了通过拆卸替换方式定位RRU故障存在的不方便的问题，实现了RRU故障的远程检测。
显然，本领域的技术人员应该明白，上述的本发明的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。
以上所述仅为本发明的可选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
