利用MMSE预编码方法求解MIMO系统和速率(MMSE precoding method for a MIMO system and rate)

说明：  两个matlab的GUI实现UDP通讯，建议在两台电脑上测试。(The two matlab GUIs implement UDP communication. It is recommended to test on two computers.)

基于压缩感知的信道估计代码，有信道模型的建立和压缩感知信号的估计(Estimated based on compressed sensing channel code, the channel model)

We have proposed a novel pilot decontamination scheme which combines the two existing schemes: SPRS and WGC-PD scheme.

说明：  自己用的小软件，仿造原子的XCOM功能，加了一下自己用的功能。 1、基本串口通讯，鼠标放入串口选择自动刷新，显示COM口的驱动类型。 2、多条发送界面，可定时发送，可关联数字键盘、右键发送按钮可更改按钮名称，方便记忆。 3、485通讯，数据有十进制和十六进制可选，发送后自动保留记录。 4、CRC校验小工具。 5、十六进制通信协议提取部分位并根据自定义数据类型转化为十进制 6、字符格式示波器，例：">P:-1.25"，示波器显示曲线名称P，数值-1.25，曲线个数最多8个。 7、类似MODBUS协议截取第2-5位，合成一个int数值，然后示波器显示波形，最多5个曲线 8、示波器曲线可键拖拽、放大(QT serial port assistant, plus digital oscilloscope)

说明：  factorialsss code in c++ and cyclic redundancy check is exceuted in c++

用simulink中s函数实现两路切换开关(S function with simulink realization of two-way switch)

MSK modulation using Simulink

说明：  qpsk在高斯信道下的仿真，包括误码率和仿真图(Simulation of QPSK in Gaussian channel)

说明：  In this paper, a new direction-of-arrival (DOA) estimation method based on multiple Toeplitz matrices reconstruction is proposed for coherent narrow band signals with a uniform linear array (ULA).(Even in the case of a low signal-to-noise ratio and low snapshot number with half the array aperture reduced, the new method provides good performance on estimation and resolution.)
