simulink_SpreadSpectrum1

主要介绍了基于MATLAB环境下的CDMA无线蜂窝系统的仿真和关键物理层技术的仿真。(Mainly based on the MATLAB environment CDMA wireless cellular system, the key to the simulation and the simulation of physical layer technologies.)

demonstrates the compressive sensing using a sparse signal in Time domain. The signal consists of a UWB (Ultra Wide Band) pulse in time domain. The signal is sparse in Time domain and therefore K random measurements are taken in Frequency domain.

说明：  遗传算法（Genetic Algorithm）是模拟达尔文生物进化论的自然选择和遗传学机理的生物进化过程的计算模型，是一种通过模拟自然进化过程搜索最优解的方法，它最初由美国Michigan大学J.Holland教授于1975年首先提出来的，并出版了颇有影响的专著《Adaptation in Natural and Artificial Systems》，GA这个名称才逐渐为人所知，J.Holland教授所提出的GA通常为简单遗传算法（SGA）。(GA (Genetic Algorithm) is a simulation of Darwinian theory of evolution by natural selection and genetic mechanism of biological evolution of the computing model is a natural evolutionary process by simulating the optimal solution search method, which originally developed by the University of Michigan J.Holland Professor in 1975 first proposed and published an influential monograph "Adaptation in Natural and Artificial Systems", GA this name was gradually known, J.Holland raised by Professor GA is usually simple genetic algorithm (SGA ).)

说明：  通过fft，求噪声功率谱的功率谱估计方法。(By fft, seeking the power spectrum of the noise power spectrum estimation method.)

列主元的Gauss消去法，此代码为防止矩阵的条件值太大，用于快速求解列主元。(The Gauss elimination method of the column principal element)

说明：  对布朗运动的方程求解 是个随机微分方程 进行求解(The solution of Brownian motion is a stochastic differential equation.)
