用Matlab进行弹道解算的主程序equationsolve

说明：  基于MATLAB/GUI的M-QAM调制解调及误码率,本文件是在MATLAB2009a版本上设计的，低于此版本的有可能会出错。 此文件中“M_QAM.m”是主文件，其他均为调用文件,该程序实现了MQAM的调制解调功能，并画出了每一步的波形 (Based on MATLAB/GUI s M-QAM modulation and demodulation and bit error rate, this document is designed MATLAB2009a version, this version is lower than might be wrong. This file is in the " M_QAM.m" is the main document, others are calling the file, the program implements the MQAM modulation and demodulation functions, and draw the waveform of each step)

说明：  matlab sym格式转换成char型和数值型的简易算法(sym convert to char or num simple algorithm )

基于matlab的低通有源滤波器设计wp=30hz，ws=40hz，rp=0.5，rs=40，fs=100hz. (Matlab-based low-pass active filter design wp = 30hz, ws = 40hz, rp = 0.5, rs = 40, fs = 100hz.)

主要是关于阵列信号处理相关代码，尤其是最优信号处理，波束的产生和仿真。(Mainly on the array signal processing-related code, especially the optimum signal processing, beam generation and simulation.)

The Hurst parameter H characterizes the degree of long-range dependence (and asymptotic selfsimilarity) in stationary time series. Many methods have been developed for the estimation of H data. In practice, however, the classical estimation techniques can be severely affected by nonstationary artifacts in the time series.

DF加中继基于门限的中继选择，适合基础者学习。(DF plus relay threshold-based relay selection, suitable foundation to learn.)
