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 r

OFDM系统，包括自适应功率和比特的分配，通过matlab实 现-OFDM systems, including adaptive power and bit allocation, by matlab

For restoration of time-domain signals, an estimate of the instantaneous magnitude spectrum is combined with the phase of the noisy signal, and then transformed via an inverse discrete Fourier transform to the time domain. In terms of comput
