这是矩阵计算一书的第二部分，由于是从网上下载的，两部分是分开的，没法合并，所以只好分两次上传，欢迎下载浏览。(This is the matrix of the second part of the book, as it is downloaded from the Internet, the two parts are separated, can not be combined, so only two upload, please download the browser.)

网络仿真软件OPNET AdHoc模型文件(network simulation software OPNET TCP model document)

说明：  本程序研究IQ误差对线性调频信号匹配滤波的影响，仿真匹配滤波后信号幅相误差特性，仿真主瓣宽度、旁瓣电平的变化(This program studies the influence of IQ error on matched filtering of chirp signal, simulates the characteristics of signal amplitude and phase error after matched filtering, and simulates the change of main lobe width and side lobe level)

这是一个去极值滑动窗口数字滤波器算法，在ADC采样的时候可以用这个算法去除脉冲干扰。(This is digital filter algorithm which removes extreme value，and it works just like a sliding window, we can use this algorithm to remove glitches in ADC sampling。)

这是一个完整的OFDM通信系统仿真代码。包括信源编码信源调制，信道编码，信道估计，峰均抑制比等。实际程序可用直接运行。(This is a complete OFDM communication system simulation code. Including the source modulation source coding, channel coding, channel estimation, peak to average ratio suppression. The actual procedure can be run directly.)

说明：  power allocation in NOMA

针对通信侦查课题，通过已知先验知识和截获信号，进行找出同步序列，匹配滤波，校正频偏和相偏，均衡，解交织，译码，恢复出原序列，最终得到的序列与原序列作对比得到误码率为0(Investigation subject for the communication, by known a priori knowledge and intercepted signal conducted to identify the synchronization sequence, the matched filter, correcting frequency offset, and phase deviations, balanced, deinterleaving, decoding, to recover the original sequence, the resulting sequence with the original sequence compared error rate is 0)

说明：  印度尼西亚大学电子学院的的OFDM程序,非常好,(The OFDM program of the School of Electronics at the University of Indonesia is very good,)

有助于学习LS信道估计的编码,以及mmse和LMMSE(ls chanel MMSE CHANEL LMMSE CHANEL)
