基于块对角化预编码系统性能分析

摘要

The processing method of BD for precoding system in multiuser MIMO system is analyzed in this paper. By designing signal transmitting and receiving filters, the MIMO multiuser downlink channel is broken down into many parallel and independent single-user channels to eliminate CCI and improve system performance. MATLAB simulation proves the validity of the method.%分析了MIMO多用户系统预编码系统块对角4E（BD：BlockDiagonalization）处理方法。通过设计信号发送滤波器和接收滤波器，将MIMO多用户下行链路信道进行分解成多个平行独立的单用户MIMO信道来处理，以消除多用户同道干扰（CCI），从而提高系统性能。MATLAB仿真结果证明了该方法的有效性。
