代码说明：

说明：基于MATLAB语言实现了BPSK、QPSK和QAM在数字通信中的误码率性能，并与理论性能进行了比较。实现了两个发射天线的分集，分析了分集提高误码率性能的原因和实质。(Based on MATLAB language, the BER performance of BPSK, QPSK and QAM in digital communication is realized and compared with the theoretical performance. The diversity of two transmit antennas is realized, and the reason and essence of diversity improving BER performance are analyzed.)
