OFDM程序

说明：  小波分解与重构源代码，其中包括图形，很简洁，望能够提供帮助(Wavelet decomposition and reconstruction of the source code)

跳频（占空比为0.5）4fsk的部分频带干扰误码率计算，这个程序是基于matlab的，自己编的，呵呵(Frequency Hopping (duty cycle 0.5) 4fsk the partial band interference bit error rate, this procedure is based on matlab, and their series, Oh)

判断一组数据服从何种分布：正态分布判，断泊松分布判断，γ分布判断，指数分布判断，rayleigh分布判断(Determine a set of data obey what distribution )

1. 给定模拟信号：，式中，，。对进行采样，可得采样序列 选择采样频率=1 kHz，观测时间ms，观测所得序列及其幅频特性 改变采样频率=300Hz，观测此时的变化 令采样频率=200Hz，观测此时的变化 要求分析说明原理，绘出相应的序列及其它们对应的幅频特性曲线，指出的变化，说明为什么？(failed to translatefailed to translatefailed to translatefailed to translate)

MatlabBGL. A Matlab Graph Library. MatlabBGL is a Matlab package for working with graphs. It uses the Boost Graph Library to efficiently implement the graph algorithms. MatlabBGL is designed to work with large sparse graphs with hundreds of thousands of nodes.

在信号处理中，往往需要考虑噪声环境下的仿真效果，此源码提供了相关色噪声的源程序。(In signal processing, noisy environments often need to consider the simulation results, this source provides a source of noise related to color.)
