Resistivity of various types of materials

针对IEEE模型的潮流计算(4节点、14节点、30节点、1047节点(Against the tide of the IEEE model calculation (4 nodes nodes, 14 nodes, 30, 1047 )

2个用户的cdma程序..比较了TDL模型在白噪声环境下和瑞利环境下模拟得出BER。(2 users cdma program .. compare TDL model in white noise environment and Rayleigh environment by BER.)

说明：  通信系统中一种常见的数字调制方法，16—QAM调制(QAM)

标准AM调制，ma不同值时的AM振幅调制(Standard AM modulation, ma different values ​ ​ of amplitude modulation AM)

直接序列扩频系统（DS，Direct Sequence）又称为直接序列调制系统或伪噪声系统（PN 系统），简称为直扩系统，是目前应用较为广泛的一种扩展频谱系统。要传送的信息经伪随机序列编码后对载波进行调制。在发信端越冬用扩频序列去扩展信号的频谱，在收信端，用相同的扩频友序列进行解扩，将展宽的频谱扩展信号还原成原始信号。因为伪随机序列的速率远大于要传送信息的速率，所以受调信号的频谱宽度将远大于要传送信息的频谱宽度，帮称之为扩频(Direct sequence spread spectrum (DS, Direct Sequence) modulation system, also known as direct sequence or pseudo-noise system (PN system), referred to as direct expansion systems, is currently the more widely used as a spread spectrum system. To send the information encoded by the pseudo-random sequence of carrier modulation. End of winter in the letter to extend the signal with the spreading sequence of spectrum, in the end prepared to receive and use the same sequence spread spectrum despreading friends, broadening the spectrum to restore the original signal expansion signals. Because the rate of pseudo-random sequence is much larger than the rate of information to be sent, so the frequency spectrum by adjusting the width of the spectrum is much larger than the width of the information to be sent to help is called spread spectrum)

一本比较全面的关于matlab在数学建模方面应用的参考书，适合参加mcm和cumcm的同学。书比较清晰，源码可以直接复制！(matlab some of the basic algorithm!)
