run

用于添加噪声，达到去噪的目的.原始数据如果不太理想，去噪是常用的处理方法(Used to add noise to achieve the purpose of de-noising. If the original data is not ideal, de-noising is a common treatment method)

The earliest work on adaptive filters may be traced back to the late 1950s, during which time a number of researchers were working independently on theories and applications of such filters. From this early work, the least-mean-square ð LMSÞ algorithm emerged as a simple, yet effective, algorithm for the design of adaptive transverse (tapped-delay-line) filters.

说明：  该程序包括了ofdm和qam两种调制的matlab仿真程序，并对两种调制方式进行了对比分析并仿真。(the program includes two QAM OFDM modulation and the Matlab simulation program, and two modulation methods for comparative analysis and simulation.)
