FunctionMatlab

这个文件编程实现了正弦调频的频谱图分布和乔伊-威廉斯分布，通过观察我们可以看到不同时频分布算法实现的不同特点(This file programming the frequency spectrum of a sinusoidal FM distribution and Joy- Williams distribution, we can see by observing the time-frequency distribution of the different features of algorithm implementation)

参考3GPP相关标准并根据LTE技术特征和关键特性，对下行链路级进行设计，包含以下步骤：比特生成、CRC校验、码块分割、编码、速率匹配、码块级联、加扰、调制、层映射、预编码、资源映射、OFDM符号生成和天线映射。为模拟无线传输信道，还需仿真相应的信道模型。收端则是发端的严格逆过程，对接收信号进行一系列处理，得到代表原始发送的信息并判决。(References 3GPP LTE technology standards and in accordance with characteristics and key characteristics of the downlink stage design, comprising the steps of: generating bits, CRC checksum, code block segmentation, encoding, rate matching, code block concatenation, scrambling, modulation , layer mapping, precoding, resource mapping, OFDM symbol generation and antenna mapping. Analog wireless transmission channel, the need to emulate the corresponding channel model. The receiving end is the inverse of the originator of the rigorous, a series of processing the received signal, the representation of the original transmitted information and judgment.)

移动丝印到器件中心的skill程序，非常实用(move refdes to the center of symbol)

说明：  用matlab编写的遗传算法和模拟退火程序(Matlab prepared using genetic algorithms and simulated annealing procedures)

实现td-scdma链路层仿真，完成传输信道和物理信道的编码和译码(Achieve td-scdma link layer simulation)

proram for k hold in matlab

他能把前后景分开，把前景去除掉，形成稳定的背景图(He can separate foreground and background, the foreground removed to form a stable background)

说明：  matlabpart2适合初学者自学matlab用，比较简单(matlabpart2 suitable for beginners and self-matlab use relatively simple)

说明：  认知无线电方面的经典著作，好书不用多言，自己看吧~(Aspects of cognitive radio classics, books do not have to say, it yourself ~)

基于matlab/simulink的双PWM逆变器仿真(based on Matlab/Simulink dual PWM inverter Simulation)
