ls 与 mmse 两种信道估计算法比较LS_MMSE

说明：  数字信号处理，利用matlab语言仿真，对信号进行滤波。(Digital signal processing, using MATLAB language simulation to filter the signal)

Two different types of measurement matrices: predefined and random measurement matrices were studied and tested using MATLAB. The speech signal was reconstructed without losing important information in order to achieve an increase in the data rates. After multiple simulations

C# 串口例子，含有Modbus通讯，已经过测试，保证可用(C# serial port example, contain a Modbus communication, has been tested to ensure that available)

说明：  利用遗传算法优化SVM的两个参数，得到高精度的SVM模型用于识别分类(Optimization of SVM parameters by GA algorithm)

2.4寸彩屏显示渐变颜色彩条，c语言编程实现(2.4 inch color screen display color tapered color strips)

这是整套的ldpc-ofdm仿真模拟代码，可以运行的，输出的是误码率图像(This is the whole set of ldpc-ofdm simulation code, you can run the output image is the bit error rate)

说明：  本程序是QPSK的AWGN通道下的误码率分析，里面包括matlab源程序，(Analysis of BER in AWGN channel of QPSK)

ofdm papr降低pts技术（三种分割法源代码）(ofdm papr)

radar basics and about two a4 sheets.

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.)
