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.)

energy efficiency code for cognitive radio

说明：  利用pluto设备实现fm调制与解调，simulink代码文件(Use pluto equipment to realize fm modulation and demodulation, simulink code file)

通信物理层处理，包括发射机和接收机，内容有前导处理，信道估计，信道编解码，BPSK、QPSK和8PSK调制与解调等。(Communication the physical treatment, including the transmitter and receiver, the content is leading processing, channel estimation, channel decoding, BPSK QPSK and eight PSK modulation and demodulation, etc )

ADMM算法 切普信号的参数估计问题 包括个数估计和频率估计(The parameter estimation of Chep signal based on ADMM algorithm includes number estimation and frequency estimation.)

使用opnet与matlab实现网络编码，源码在说明文档中有下载地址(Using opnet realize network with matlab coding, source code in the description in the document have Download)

利用MCMA对bpsk,qpsk,8psk进行盲均衡，并且求取误码率画出星座图(The use of MCMA on BPSK, QPSK,8PSK blind equalization, and calculating BER draw the constellation diagram)

计算机网络实验做得串口，非原创，只是为了下载方便。(Computer network experiments do serial port, not original, just for download convenience.)

说明：  中频信号正交采样（数字下变频）单频信号、 BPSK信号的低通滤波法(signal quadrature sampling (digital down conversion) for single frequency and BPSK signal use Low pass filtering)

又一个利用网上寻呼提供商的web页面来发送网上寻呼的程序，可以支持很多提供商。(Another program which uses web pages of internet call provider to send internet calling , and supports many providers)
