对文献《Simulation Models With Correct Statistical Properties for Rayleigh Fading Channels》提出的Rayleigh信道模型的仿真，仿真了信道的自相关，互相关，以及四阶统计量。仿真结果与文献一致。目前PDF的仿真的效果不好，还未奉上。关于LCR,AFD也没有做。但是总体说来，目前的仿真结果与文献是完全符合的。对应的文献也放到压缩包了。(This matlab code for paper, <Simulation Models With Correct Statistical Properties for Rayleigh Fading Channels>.This papar is very popular in channel estimation simulation.The paper is also upload with the code.)

说明：  用 schwarz模型方程积分表达建立的电弧模型，(a simulation of schwarz arc model using matlab )

vdsl场景下，不考虑串扰的matlab程序 ，包含DMT及动态比特分配(vdsl scenarios, without considering the crosstalk of the matlab program, including DMT and dynamic bit allocation)

置信传播(belief propagation,BP)算法的计算复杂度较高，且变量节点和校验节点间信息传递的信息可靠，但是迭代的实现，就最大似然算法来说，验证其提高译码性能的特点。 (Belief propagation (belief propagation, BP) higher computational complexity of the algorithm, and reliable information between variable nodes and check nodes of information transmission, but the realization of the iteration, the maximum likelihood algorithm, the verification of its improved decoding performance characteristics.)

用数学的思想编写出的生成均匀分布的1000个随机数，数学思想可参照之前上传的论文(Mathematical ideas to write the generated 1000 uniformly distributed random number,)

包括现代数字信号处理中的四种信号变换：FTF、LMS、LSL、RLS的matlab源代码。(Including modern digital signal processing of four kinds of signal conversion: FTF, LMS, LSL, RLS the matlab source code.)

MIMO系统容量仿真程序分为两个。其中 文件夹1为：发射天线数为4，接收天线数逐渐增大时MIMO系统容量的仿真程序。 文件夹2为：接收天线数为4，发射天线数逐渐增大时MIMO系统容量的仿真程序。(MIMO system capacity simulation program is divided into two. One folder 1 as follows: the number of transmitting antennas is 4, gradually increasing the number of receive antenna MIMO system capacity when the simulation program. Folder 2 as follows: the number of receiving antennas 4, gradually increasing the number of transmission antennas, MIMO system capacity when the simulation program.)

说明：  同态滤波使图像亮度较暗的区域变得可见，而高亮区也变得更加清晰，对比度增强，图像可视化程度增加。(homomorphic filtering )
