    衡量一个数字通信系统性能好坏的指标很多,误码率性能就是一个重要的指标。误码率是指错误接收的码元数载传输总码元数中所占的比例。在该章中,我们将通过MATLAB仿真在发送平均功率和传输速率相同的情况下(A digital communication system performance measure indicators of good or bad a lot of bit error rate performance is an important indicator. Bit error rate refers to the number of errors contained in received transmission symbol the number of total yards per share. In this chapter, we will send through MATLAB simulation of average power and transmission rate in the same circumstances)
