信号的滤波频谱分析

this file talk about network

说明：  repeat-accumulate codes (RA codes)

用 MATLAB 对基带数字通信系统进行仿真。整 个系统模拟了发送和接收的全过程。其中调制部分采用 16QAM，并且采用基带传输(Using MATLAB for baseband digital communication system simulation. The system simulates the entire process of sending and receiving. Where the modulation part is 16QAM, and using the base band transmission)

实现串口通信 可以收发数据 可以是数字也可以是ASCII(Serial communication)

通过c语言编程实现can通信中的数码管驱动问题。经过实验验证，该代码完全可行(C language programming through the digital communication can drive problems. Experimental results show that the code entirely feasible)

通信系统仿真原理与无线应用 《通信系统仿真原理与无线应用》系统地介绍通信系统的设计、分析和仿真方法，还提供了大量极具参考价值的仿真实例。(Simulation principles of communication systems and wireless applications. "A systematic introduction to the design, analysis and simulation of communication systems, it also provides a large number of simulation examples of great reference value.)

PMA规约模拟测试软件。适合初学者使用，包含几个常用规约(PMA Statute of the simulation test software)

说明：  最简单的收发程序，可以用于超宽带测距，信道通信等等(The simplest transceiver program can be used in UWB ranging, channel communication and so on)

OFDM_cyclic_spectrum11,循环谱切片谱的一些原理性matlab代码(this is matlab code about OFDM_cyclic_spectrum)

生成服从gamma-gamma分布和对数正态分布的随机信号(generate gamma-gamma distributed signals)
