improved_jakes
- This code implies the improved Jakes Method( Y. R. Zheng and C. Xiao, Improved models for the generation of multiple uncorrelated Rayleigh fading waveforms, IEEE Comm. Lett., vol. 6, no. 6, pp. 256-258 (2002) ) to simulate Rayleigh fading -This c
nlpf
- This simple Matlab function simulates a innovative algorithm for narrow band interference mitigation for wireless communications, esp for satellite comm. The algorithm looks similar to LMS, but error is non-linearly transformed. It works well and a

- 新型改进光双二进制传输的编解码方案 提出了改进型光双二进制信号在高速率(≥10Gbit／s)传输时预编码的一种新方案。通过分析编解码过 程，证明该信号传输时不易受码间干扰影响，能用二进制强度调制一直接检测的系统接收信号。仿真产生了该信 号的2种码型。结果表明，采用色散补偿技术能使MD NRZ和MD．RZ信号在长距离传输后克服眼图失真，MD-RZ 信号比MD．NRZ信号在传输后有更低的误码率。-Abstract：Anovel pre-coding schemeformodified

LDPC
- LDPC码是通过校验矩阵定义的一类线性码，为使译码可行，在码长较长时需要校验矩阵满足“稀疏性”，即校验矩阵中1的密度比较低，也就是要求校验矩阵中1的个数远小于0的个数，并且码长越长，密度就要越低。 -LDPC Coding with PSK modulation in Rayleigh fading channel Most of the functions are built in matlab functions found in the comm. toolbox. These
CurveLab-2.1.2
