coherence_MVDR
基于MVDR算法,计算两个信号的相关性的函数。(This program computes the coherence function between 2 signals
x1 and x2 with the MVDR method.
This algorithm is based on the paper by the same authors:
J. Benesty, J. Chen, and Y. Huang, "A generalized MVDR spectrum,"
IEEE Signal Processing letters, vol. 12, pp. 827-830, Dec. 2005.
x1, first signal vector of length n
x2, second signal vector of length n
L is the length of MVDR filter or window length
K is the resolution (the higher K, the better the resolution))

LDPC码编译码算法的研究与实现_李会雅
本文首先介绍了几种LDPC码的编译码算法,同时推导了译码错误概率和密度进化
过程,讨论了信道参数的门限效应。接着对LDPC码二分图中长度为4的环进行了深入
研究,提出了一种LDPC码校验矩阵的消4一环生成算法,采用Matlab和VC++融合编程
方式,完成了此算法的程序设计。此算法不仅可生成二进制LDPC码的校验矩阵,并且
对算法修正后,也可生成多进制LDPC码的校验矩阵。采用此算法后可避免LDPC码译
码过程中的重复迭代,显著提高了短帧LDPC码的误比特率性能。同时对不同参数对
LDPC码性能的影响进行了仿真,得到了一些结论。最后,利用VHDL语言在复杂可编
程逻辑器件(CPLD)上完成了LDPC码编码器的硬件实现。另外,给出了LDPC码译
码器硬件实现的整体结构图,结合对数似然比域内的置信传播迭代译码(LLR-BP)算
法,对译码器的各个模块进行了详细阐述。(Research and implementation of LDPC coding and decoding technology)
