中文说明：利用matlab实现OFDM算法，其中包含调制解调，计算信噪比，利用QAM进行调制，进行误码率统计，并且BER曲线绘制以及峰均比CCDF曲线部分
English Description：
Algorithm for OFDM based on MATLAB, including modulation and demodulation, calculate the signal to noise ratio, using QAM modulation, bit error rate statistics, and BER curves and the PAPR CCDF curve segments
