RLS Channel estimation of MIMO-OFDM System

国外经典教材《神经网络设计》的演示程序NNARROW.W，非常经典、难得。本书书写非常优秀，演示程序同样如此。(Foreign classic textbook " Neural network design," the demo program, very classic, rare. This book is very good writing, presentation program the same way.)

QAM Modulation

数学应用中的25个matlab程序，绝对经典，对初学matlab编程有很好的参考价值。(Mathematical applications in matlab program 25, an absolute classic, matlab programming for beginners have a good reference value.)

短时傅里叶变化的程序， 可以2d显示，也可以3d显示，短时傅里叶变化的结果。(Short-time Fourier transform of the process, can be 2d show can also be 3d shows the result of short-time Fourier transform.)

伺服控制数学模型，matlab 程序，轻松搞定算法(Servo-control mathematical model, matlab program, easy to get algorithm)

多输入多输／出(MIMO)雷达具有多个发射天线阵元和多个接收天线阵元，每个 阵元发射不同的信号且发射信号相互正交。(Multiple-input multiple input/output (MIMO) radar has multiple transmit antenna elements and multiple receive antenna elements, each element emission signal and transmit signals orthogonal to each other.)

本文先用灰色GM(1,1)模型对陕西省GDP 做预测, 经过检验, 再用此模型确定另外一些未知指标, 最后通过确定的这些指标用 灰色GM(1,N)模型作预测, 通过比较总结两种模型各自的特点, 从而科学的指导陕西省经济发展,国内生产总值预测模型具有重要的现实意 义。 (This article first gray GM (1,1) models do forecast GDP of Shaanxi province, on examination, then this model to determine other unknown targets, and finally through the identification of these indicators of gray GM (1, N) model for prediction, by Comparison of two models summarize the characteristics of their own, so the guidance of scientific economic development in Shaanxi Province, China' s GDP forecast model has important practical significance.)

通过编写C语言，在MATLAB上实现路由器仿真,实现路由器的功能。(Written by C language, simulation on MATLAB implementation routers, realize the function of the router. )

发送装置：随机信号产生、脉冲成型（上采样可调，滚降可调）； 发送：AWGN信道（信噪比范围可调） 接收设备：QPSK调制解调 ，匹配滤波，判决 画出接收信号的眼图、星座图；计算误码率并与理论值比较。 (Transmitting device: random signal generator, pulse shaping (the sampling adjustable, adjustable roll-off) Send: AWGN channel (SNR range is adjustable) Receiving equipment: QPSK modulation and demodulation, matched filtering, judgment   BER is calculated and compared with the theoretical value draw the received signal eye diagram, constellation.)
