说明：  运行主函数qam.m，可得到调用理论误符号率曲线和仿真结果。仿真结果包括误符号率和误码率。(running qam.m main function will receive the symbols mistakenly called theoretical curve and simulation results. Simulation results include misuse of the symbol rate and bit error rate.)

说明：  地震记录显示 显示地震记录波形 振幅等 地震记录(Seismic Record Display)

此实验是关于详细的采样定理，有设计与实现及MATLAB程序代码。(It is useful.)

reduction to papr in ofdm with Peak Windowing: The basic idea of peak windowing is to multiply the envelope of OFDM signal with a weighting function . Therefore, ~xE (t)= xE (t) f (t) where XE(t) =[x(t)] The weighting function given by: f (t)= 1-Σ α .w(t- t ) t-t w(t) : is the window function. t : denotes the position of a local maximum of the envelop xE(t) . α : attenuation constant . When the amplitude of envelop amplitude of the OFDM signal exceeds a threshold, a window function is applied to the envelop of the OFDM signal to eliminate the peak amplitude. windowing results in a smooth signal. Hanning window function will be used for w(t) As a matter of fact , other windows such as cosine, hamming and Kaiser may be employed.
