Model a signal using Shanks method

计算机网络数据链路选择性重传实验。 　　设计一个滑动窗口协议，在仿真环境下编程实现有噪音信道环境下两站点之间无差错双工通信。信道模型为8000bps 全双工卫星信道，信道传播时延270毫秒，信道误码率为，信道提供字节流传输服务，网络层分组长度固定为256字节。(Computer network data link selective retransmission experiment. Design of a sliding window protocol in simulation programming environment there is no error duplex communication channel between the noisy environment the two sites. Channel model is 8000bps full-duplex satellite channel, the channel propagation delay 270 ms, channel bit error rate, channel provides a byte stream transmission services, network layer packet length is fixed at 256 bytes.)

整理出的一个关于mimo天线选择的程序，用matlab编写的，希望对大家有用(Sorted out the program using matlab mimo antenna selection)

k-means clustering is a method of vector quantization, originally signal processing, that is popular for cluster analysis in data mining. k-means clustering aims to partition n observations into k clusters in which each observation belongs to the cluster with the nearest mean, serving as a prototype of the cluster. This results in a partitioning of the data space into Voronoi cells.

对一个无向图求其最小生成树，图用邻接矩阵表示(Find the minimum spanning tree)

这个matlab程序主要介绍的而是OFDM调制过程，主要设置了符号数，载波数，循环前缀大小，对信号进行了IFFT变换，串并转换等。(The matlab program introduces the OFDM modulation process but the main set of symbols, the number of carriers, cyclic prefix size, the signal of the IFFT transform, string and conversion)
