This is an OFDM CODE

说明：  对数字信号进行BFSK调制，然后通过高斯白噪声信号后，检测其误码率！(The program s function is to modulate a signal with BFSK,then let the signal go pass a channel of guassian white nosie.At last,The program detects the BER of the signal.)

Digital Image Enhancement source code with GUI in MATLAB very good explained

在平稳瑞利多径信道下，用BPSK调制，用matlab 仿真由最大似然译码的性能。(It discuss a receiver structure called Maximum Likelihood (ML) decoding which gives us a better performance. We will assume that the channel is a flat fading Rayleigh multipath channel and the modulation is BPSK.)

一维信号的小波变换原程序，用MATLAB编写的。对于初学者理解小波变换的含义非常有帮助。(One-dimensional wavelet transform of the original program, written using MATLAB. Wavelet transform for beginners to understand the meaning very helpful.)

this will help u on cdma system this will provide u matlab on cdma system

说明：  文章详细分析了OFDM技术的实现原理，用MATLAB软件对OFDM的传输性能进行了仿真模拟并对结果进行了分析。(The article detailed analysis of the OFDM technology to achieve the principle of OFDM using MATLAB software for the transmission performance and simulation results are analyzed.)

通过给出的随机过程，该随机过程是由3个实正弦信号组成，归一化频率分别为0.1,0.25,0.27，其中相位是相互独立在【0,2*pi】上分布的随机相位；噪声是均值为0、方差为1的实高斯白噪声，信噪比为30db,30db,27db,观测样本数为N，通过bartlett法，Welch法，周期图法计算随机过程的概率谱(Given by stochastic process, the stochastic process is composed of three real sine signal, the normalized frequency were 0.1, 0.25, 0.27, including phase is independent in [0, 2* PI] on the distribution of random phase Noise variance is the mean to 0, 1 real gaussian white noise, signal to noise ratio of 30 db, 30 db, db, and the observation sample for N, by bartlett, Welch, periodogram spectrum method to calculate the probability of the random process)

该源码是一些代码程序，现上传上去望大家指正(The source code is a number of procedures is up hope you upload correction)
