Reed-Solomon-with-QPSK

关于滤波器性能的各种转换 帮助菜鸟在较短时间内精通滤波器性能的MATLAB表示(About the performance of a variety of conversion filter to help rookie proficient in a relatively short time the performance of MATLAB filter express)

汪裕民的OFDM关键技术与应用中仿真MIMO-OFDM的源代码，个人做了些改动，但是误码率比较大，望大牛帮忙调一下(汪裕public key technology and application of OFDM in MIMO-OFDM simulation of the source code, made some personal changes, but the error rate is relatively large, look like large cattle to help tune)

说明：  用ar方法估计功率谱，并估计信号频率和峰值(Ar method estimates the power spectrum, and estimate the signal frequency and peak)

一个实用的傅里叶分解程序,程序可以输出源曲线和频谱图(a fourier analysis function, which outputs the orgrinal curve and frequncy map of components)

说明：  This code is related to the course Digital Communications. It simulates a communication system which uses AWGN and 16QAM

本文针对基于经验模态分解ＥＭＤ的时空滤波器存在的固有模态函数分量中频率混叠交叉导致有用信号与噪声一起被滤除的问题结合小波在时间尺度两域表征信号局部特征的特性提出了一种基于能量估计实现ＥＭＤ分解层数确定(In this paper, based on empirical mode decomposition EMD temporal filter mode functions inherent component of cross-frequency aliasing and noise together lead to useful signal is filtered in the time scale of the problem combined with wavelet domain characterization of two local features of the signal characteristics of proposed achieve energy estimation based on EMD decomposition level determined)

MATLAB code for the simulation of Channel DVB-S

集合dsb调制与解调完整程序，很辛苦找到的(A complete set of FSK modulation and demodulation process, it is hard to find)

Comparison of performance for 2-PPM and 2-PAM under two pulse shapes, Gaussian Pulse and Hermit Pulse with Three scenarios are considered (5, 20, and50 users).

这个程序得到的lambda_1不能当做最大lyapunov指数，因根据所作出的曲线选择线性区进行拟合，此处的处理是为了程序的方便 (This program was not as maximum lyapunov lambda_1 index, based on curve fitting due to the linear region selection made, in order to deal with here is a program of convenience " )
