信号检测是长期演进( LTE)系统接收端的一项重要技术，对系统的性能有着较大的影响。在LTE系统中，接收端的天线同时接收来自发送端的多个天线端口的数据，因此接收端必须采用信号检测算法还原发送端的数据。分析与研究了基于传输分集的信号检测算法，并着重讨论了空频编码法，提出了一种简单的DSP实现方案。该方案已成功应用于TD-LTE TTCN扩展测试集仪表开发项目中。

Signal detection is one of the significant technologies for receiving terminal in long term evolution ( LTE) system, it highly influences the system performance. In LTE system, the receiving antennas at receiving end simultaneously receive the data coming from multiple transmitting antenna ports, so it is necessary to use signal detection algorithm at the receiving end to restore the data from transmitting end. The signal detection algorithm based on transmit diversity is analyzed and studied, and the space frequency block coding ( SFBC ) method is discussed emphatically, and the simple DSP implementing scheme is proposed. The scheme has been successfully applied in development of the TD-LTE TTCN extended test suite instrumentation.
