the same with what i have uploaded before.

16QAM调制解调，不用系统自带命令，完全按照调制解调系统进行。(16QAM modulation and demodulation, without the system comes with command, in full accordance with modulation and demodulation system.)

说明：  用MATLAB编写的crc检验查表法程序(Prepared using MATLAB CRC test procedure look-up table method)

最小二乘递推算法辨识程序, 输入信号为正态分布白噪声 (RLS identification procedures for the normal white noise input signal)

RS编码的matlab仿真,对加入突发噪声信道的RS（15，11）编码进行的仿真.(RS coding matlab simulation, burst noise channel to join the RS (15,11) code for simulation.)

说明：  基于非相干信号字空间宽带源DOA估计方法，代码可运行(The matlab code is the DOA estimation for wide-band signals by ISM. It works well.)

matlab实现的MME（modified matrix encoding）隐写算法 可成功运行(the MME (modified matrix encoding) steganographic algorithm which can successfully run)

利用firpmord和firpm函数设计双带通滤波器，其指标为，第一带通指标：f =4kHz,f =5 kHz ,f =3.6 kHz ,f =5.4 kHz 第二带通指标：f =6kHz,f =7 kHz ,f =5.6 kHz ,f =7.4 kHz 通带衰耗A <3dB，阻带衰耗A >40dB，抽样频率f =20kHz。(Double belt pass filter using firpmord and firpm function design, for its indicators, through the first area index: f = 4 kHz, f = 5 kHz, f = 3.6 kHz, f = 5.4 kHz The second bandpass indicators: f = 6 kHz, f = 7 kHz, f = 5.6 kHz, f = 7.4 kHz Pass band attenuation A < 3 db, stop-band attenuation A > 40 db, f = 20 KHZ sampling frequency.)

matlab编写的匹配滤波器,适用于信号相关处理，(match-filter with matlab)

基于广义MUSIC的相干分布式信号源的DOA估计(Distributed coherent signals DOA estimation based on the MUSIC algorithm)
