仿真了跳频系统中并行捕获的性能，希望对大家有帮助(parallel acquisition )

第15章 常微分方程的初值问题.zip。是从书中光盘里直接拷贝的代码，放在这里，与大家共享，共同交流，希望对大家有帮助。(Chapter 15 of the ordinary differential equation initial value problem)

生成一个规则LDPC码的教研矩阵H，其行数(越大越好)为列数的一半，行重为6，列重为3，任意两行没有围长为4的圈 使用方法：H=HGrandom2(m,n)。m表示行数，n表示列数(rules of a generation of research LDPC matrix H, its (larger the better) half of the series, re-6, series of three, two arbitrary line is not girth of the ring used four methods : H = HGrandom2 (m, n). Said a few m, n Columns)

3G里使用的Spreading技术演示仿真。用于教学演示的Matlab模型。A demo of spreading code generation and modulation used in 3G.(3G Lane Spreading the use of simulation technology demonstration. Teaching Demonstration for the Matlab model. A demo of spreading code generation and modulat ion used in 3G.)

this is a simple and comfort system for recording voice

说明：  粒子群优化算法的基本思想是通过群体中个体之间的协作和信息共享来寻找最优解．(Particle swarm optimization algorithm based on the idea that groups of individuals through collaboration and information sharing to find the optimal solution.)

说明：  谱减法的测试程序，能够测试谱减法的去噪能力以及相关信息。(Spectral subtraction of test procedures to test spectral subtraction denoising and related information)
