在MIMO-ofdm系统中，空时分组编码STBC对系统性能的测试，给出信噪比和误码率的关系图形。-In the MIMO-ofdm systems, space-time block coding STBC on the system performance test, given the relationship between SNR and bit error rate graphics.

程序中以一根接收天线为例，分别对一根发射天线、两根发射天线、三根发射天线和四根发射天线系统进行STBC仿真。比较误码率性能。-Program to a receiving antenna, for example, a transmitting antenna, respectively, the two transmit antennas, three transmit antennas and four transmit antenna system STBC simulation. Co
