说明：  CCSDS推荐的LDPC编码方案，一系列参考标准，很好哦！(CCSDS recommended LDPC coding scheme, a series of reference standards, very good!)

《通信系统仿真原理与无线应用》MATLAB源代码，在pudn网上也看到有这个代码，但是那个不全，有好几章代码没有，这个完整版的。(Communication System Simulation principle and wireless applications. "MATLAB source code, in pudn online to see this code, but incomplete, Several chapters code is not the full version.)

说明：  BOC调制的Matlab程序仿真及Simulink模型(Matlab program and BOC modulation simulation model of Simulink)

本文档，分别描述了LTE上行PUSCH信道，PUCCH信道，PRACH信道的基带信号处理流程(This document describes the LTE Uplink PUSCH each channel, PUCCH channel, PRACH channel baseband signal processing)

说明：  通过运用t2f f2t函数运行gmsk(Running GMSK with t2f F2t function)

利用matlab GUI实现的串口编程例子，独立成分分析算法降低原始数据噪声，构成不同频率的调制信号。( Use serial programming examples matlab GUI implementation, Independent component analysis algorithm reduces the raw data noise, Constituting the modulated signals of different frequencies.)

Implementation of Adaptive Modulation and Coding Techniques using Matlab

建荣蓝牙芯片的相关资料，常用的工具，文档说明(Info Jianrong Bluetooth chip, commonly used tools, documentation)

说明：  4. 试说明卷积编解码的工作原理： (1) 使用Simulink仿真卷积编码，并用Viterbi译码的方法进行解码，其中的编码、译码全部是自己编写代码(S-Function方式)，不是调用Simulink的已有编码、译码函数。 (2) 请在加性白高斯噪声信道中，画出比特信噪比与误码率的关系曲线。(4. Try to explain the working principle of convolutional codec: (1) Simulink was used to simulate convolutional coding, and Viterbi decoding method was used for decoding. The coding and decoding were all written by oneself (s-function method), rather than calling the existing coding and decoding functions of Simulink. (2) in the additive white gaussian noise channel, please draw the curve of the relationship between bit signal-to-noise ratio and bit error rate.)

仿真分析了步进频率雷达信号的波形频谱和模糊函数(The waveform spectrum and ambiguity function of stepped frequency radar signal are simulated and analyzed.)
