一个刚编出来的K—means 聚类算法的matlab源代码 适合多维数据(Just made out of a K-means clustering algorithm matlab source code for multi-dimensional data)

有关相位测量方面相关的一篇文章，可以帮助大家掌握更多的方法。(The article related to the phase measurement can help to have more methods.)

nearestSPD works on any matrix, and it is reasonably fast. As a test, randn generates a matrix that is not symmetric nor is it at all positive definite in general.

说明：  对中继系统中的呼叫阻塞删除系统的阻塞率进行仿真，并与理论值比较(Call of relay blocking system to delete the blocking rate of the simulation system, and compared with the theoretical value)

编写一个含QAM传输的发送和接收模块 1)分别采用复基带仿真和实带通仿真两种形式 a) 实带通仿真时, 载波频率为符号率的4倍 b)发端采用滚降系数0.5的根号升余弦滤波器 2)画出Eb/N0=15dB时的接收波形(收滤波前),取100个采样 3)画出发端输出的眼图和收端过匹配滤波后的眼图(画眼图时不加噪声) 统计误符号率和误比特率与Eb/N0的关系,画出曲线, 与理论计算的曲线相对比 (Prepare to send of one with QAM transmission and receiver module 1), respectively, the complex baseband simulation and the real band-pass simulation in two forms a) the real band-pass simulation, the carrier frequency used for the symbol rate of 4 times b) the originator roll-off factor of 0.5 root raised cosine filter, 2) draw Eb/N0 = 15dB when the received waveform (closing filter), take 100 samples) to draw the originator of the output eye diagram and income side of the eye diagram after the matched filter ( draw the eye diagram without noise) statistics symbol error rate and bit error rate and Eb/N0, draw a curve calculated with the theoretical curve compared)

Bandwidth (signal processing) or analog bandwidth, frequency bandwidth or radio bandwidth: a measure of the width of a range of frequencies, measured in hertz Bandwidth (computing) or digital bandwidth: a rate of data transfer, bit rate or throughput, measured in bits per second (bps) Spectral linewidth: the width of an atomic or molecular spectral line, measured in hertz
