LDPC码

说明：  OFDM信道估计的主要程序，算法研究等。(OFDM channel estimation algorithm for the main program, etc.)

说明：  通过matlab来实现带通滤波，可自由设置带通范围，滤波效率高，结果精确(Through MATLAB to achieve band-pass filtering, the band-pass range can be set freely, the filtering efficiency is high and the result is accurate)

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.)

opnet中aodv协议的模型，大家自己看好了(opnet in aodv protocol model, we own a good)

说明：  生成2KHz和8KHz的混合信号,使该信号通过上述滤波器,观察滤波前后的波形变化和频谱分布情况, 在改信号中加入高斯白噪声,(The mixed signal of 2KHz and 8KHz is generated so that the signal passes the above filter, the waveform change and spectrum distribution before and after filtering are observed, and Gao Si white noise is added to the modified signal.)

VB写的一个简单的服务器与客户端程序，可以进行简单的本机通讯。经修改可以用于双机通讯。(VB to write a simple server and client, can be simple local communication. Modified can be used for two-machine communication.)

matlab计算数据的AMR、ATR、RMS等特征值(calculate AMR and ATR of the data)

说明：  关于ofdm系统中ml检测信号的算法，供大家参考(ML detection algorithm for OFDM system)
