信号为两个正弦信号加高斯白噪声，用burg递推法对其进行功率谱估计，效果不错。(Signal for two sinusoidal signal plus Gaussian white noise, the recursive method burg its power spectrum estimation, good results.)

粒子群求解无约束优化问题，包括基本粒子群算法，改进的粒子群算法，还有基于自然选择的粒子群算法和模拟退火的粒子群算法(Swarm for unconstrained optimization problems, including particle swarm algorithm, the improved particle swarm optimization, as well as natural selection based on PSO and simulated annealing particle swarm algorithm)

WIMAX系统下行仿真，采用matlab语言实现，包括编码解码，子载波映射等(WIMAX system downlink simulation using matlab language, including encoding and decoding, sub-carrier mapping)

人工蜂群算法matlab源程序，实现利用蜂群算法最优化问题(artificial bee colony algorithm)

该程序主要说明直扩系统抑制正弦干扰方面的有效性。绘出不同幅度的正弦干扰信号及无干扰时的误码率.( This procedure mainly showed that expands the system to suppress the sine disturbance aspect straight the validity. Draws the different scope the sine unwanted signal and does not have when the disturbance error rate. )

说明：  用小波和小波包对太阳黑子数据进行降噪处理(Using wavelet and wavelet packet noise reduction processing on the sunspot data)

this source code find minimum,maximum ,mean and variance of image databases and store them in file named exemplars.mat

ofdm.m为主程序，可以运行，将得到迭加噪声之后的误码率曲线，并与理论QPSK加高斯白噪声误码率曲线比较，两者将重合(ofdm.m-based program, you can run, will be after the noise superposition error rate curve, and with the theoretical QPSK plus white Gaussian noise bit error rate curves, which will coincide)

说明：  bp算法，经过运行测试，没有问题，值得使用(bp algorithm, after running the test, no problem, it is worth using)
