本程序对OFDM这一调制方式的基本流程进行了仿真，通过高斯白噪声信道，接收信号解调，对比发送和接收信号波形，并画出功率谱密度图形-This program OFDM modulation scheme of this basic flow of the simulation carried out by white Gaussian noise channel, the received signal demodulation, compare sent and received signal

Its a research paper from ieee In this letter, analytical expressions are derived for the power spectral density (PSD) of orthogonal frequency division multiplex (OFDM) signals employing a cyclic prefix (CP-OFDM) or zero padding (ZP-OFDM) time

ofdm system simulation including 16qam modulation fft windowing modules plus cp, Calculating a target and ocean echo power spectral density, Mutual information is useful to calculate a set of procedures.
