Bacteria foraging algorithm for optimisation of anything...

二维正态分布的检验函数，如果需要进行二维正态分布的检验，在你的程序运行前运行此程序，就可直接调用函数功能。(Dimensional normal distribution test function, if you need a two-dimensional normal distribution test, run your program before you run this program, you can directly call the function function.)

说明：  matlab实现（2.1.3)卷积编码，已经通过调试过程，可以直接下载使用(matlab implementation (2.1.3) convolutional coding, has been through the debugging process, you can directly download)

在matlab中生成单边指数调幅信号． y=amexpols(N,t0)Ｎ生成信号的点数，t0函数的起始点，y返回信号．(generated in Matlab unilateral index AM signal. Y = amexpols (N, t0)- N signal points, the starting point t0 function, y return signal.)

内部资料，很经典的MIMO和OFDM的课本程序，以供大家参考(it is important MIMO-OFDM program)

低通IIR数字滤波器设计，用数字滤波器的单位脉冲响应序列h(n)模仿模拟滤波器的冲激响应ha(t),令 h(n)=ha(nT)，其中T为采样间隔。将模拟滤波器转换成数字滤波器的实质是，用一种从s平面到z平面的映射函数将Ha(s)转换成H(z)。数字滤波器的频率响应模仿模拟滤波器的频响，s平面的虚轴映射z平面的单位圆，相应的频率之间成线性关系。(Low-pass IIR digital filter design)

通过matlab仿真了Saleh-Valenzuela 信道模型，仿真图有四个子图，（a）和（b）分别示出的分布的群集抵达时间和射线到达时间，（c）表示S-V信道的脉冲响应，（d）图显示了信道功率分配(Saleh-Valenzuela channel model by matlab simulation, simulation diagram there are four sub-chart, (a) and (b) respectively illustrated the distribution of cluster arrived in time and the ray reaches the time, (c), said the SV letter tract of the impulse response (d ) The figure below shows the distribution of channel power)

共形阵列，球形阵列DOA估计，music算法，实用(Conformal array, sphere array DOA estimation, music algorithm, practical)
