基于OFDM的多准则下认知无线电资源分配问题的研究,认知无线电资源分配(Cognitive radio resource allocation problem of OFDM multi-criteria research, cognitive radio resource allocation)

使用matlab进行毫米波信道模型仿真，很棒的源码(Millimeter-wave channel model simulation using matlab, great source code)

说明：  雷达动目标检测仿真，含脉冲压缩，mtd处理等(Radar moving target detection simulation, including pulse compression, mtd processing, etc.)

说明：  matlab 蓝牙调试的一个例子 示例演示如何识别和连接蓝牙设备，发送(This example shows how to identify and connect to a Bluetooth device, send a message, and read data.)

OFDM调制发射和接收仿真，考虑两种调制方式，16qam及qpsk调制，使用LS信道估计和频域均衡(OFDM modulation transmission and reception simulation, considering two modulation modes, 16QAM and QPSK modulation, using LS channel estimation and frequency domain equalization.)

产生正弦信号时域波形及频谱，并通过希尔伯特滤波器。其中希尔伯特滤波器有两种产生方式，一是使用MATLAB自带的FDAtool；二是程序编写。(The time-domain waveform and spectrum of sinusoidal signal are generated and passed through Hilbert filter. There are two ways to generate Hilbert filter, one is to use FDAtool in MATLAB, the other is to write programs.)

生成常见的混沌映射，用于混沌扩频码的设计。应用三种量化方法，比特量化、门限量化以及模2量化。重点计算其相关性能，自相关以及互相关，得到相关图像。计算序列的游程、平衡度。(To generate common chaos maps and use them to design the chaotic spreading sequences. We applied three kinds of quantization methods with bit queantization, threshold quantization and mod 2 quantization. We emphasized on the calculating the correlation performance on auto-corrrelation and cross-correlation and plotted their images.)

simulink搭建的卫星姿态动力学仿真，参考书籍是章仁为的卫星鬼道姿态动力学仿真，想学对卫星姿态有兴趣的同学强烈推荐，(simulink to build the satellite attitude dynamics simulation, reference books is Zhang Ren ghosts satellite attitude dynamics simulation, I wanted to learn for students interested in satellite attitude is strongly recommended,)

基于特征函数的张量分解相关代码，结合“lm”，“als”等很多算法。 主要用于处理欠定MIMO系统识别(Based on the characteristic function of the tensor decomposition of the relevant code, combined with the " lm" , " als" and many other algorithms. Mainly used for underdetermined MIMO system identification process)
