一个很好的求信号包络的MATLAB工具包.-A good demand signal envelope of MATLAB tool kit

信号包络分析，对信号进行包络分析，求出上包络，和下包络信号-Analysis of signal envelope

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 give
