超宽带脉冲幅度调制路径损耗的计算，与其他的几个共用(Ultra-wideband pulse amplitude modulation path loss calculations, and some other common)

PCA仿真程序,主要是讲pca的算法，很明了(failed to translate)

一个卡尔曼滤波程序 利用Matlab实现 本人亲自试验可行(Kalman Filtering with Matlab implementation process)

平面刚架结构计算，能够输出结构内力和位移图形。但是在用之前要自己编辑节点信息和作用力信息(Plane frame structure calculation)

本程序仿真了AWGN信道下，采用DS扩频对bpsk信号的影响，扩频码采用walsh码，扩频因子16； 接收端进行rake接收，然后分集合并，比较了三种分集方式对误码率的影响 从图像可以看出在扩频因子较高的情况下，最大比值合并与等增益合并性能相近(This program simulates the AWGN channel, using DS spread spectrum signal for bpsk influence spreading code using walsh code spreading factor 16 Rake receiver receiving end, and diversity combining, diversity compares three methods on the bit error rate of As can be seen from the image in the case of higher spreading factor, the maximum ratio combining and equal gain combining similar performance)

Linear prediction follows naturally from the general mathematics of linear systems. As the system output is defined as a linear combination of past samples, the system’s future output can be predicted if the scaling coefficients bj and ak are known.

本例程序计算了光拍频和光多普勒效应的演示程序(beat frequency caculate)

频率域扫描建模，可以匹配传递函数，很实用的仿真。(Scanning frequency domain model, can match the transfer function, it is useful simulation.)

This is code to simulation of AM, FM, PSK, QAM modulation

actac. matlab file very good
