[Windows Mobile] MatlabprogrammsforencodinganddecodingofLDPCcodesov DL : 0: There is an example of how to use the LDPC encode/decode with AWGN channel model in files .\ldpc_decode.m and .\GFq\ldpc_decode.m. There are a few parity check matrices available in the code but you can use other matrices provided you have enough memory to load them. I suggest checking out matrices in Alist format available on David MacKay s web site.You will need to have access to a MEX compiler to be able to use a few functions written in C.

[Special Effects] UPLOAD_LY1 DL : 0: 图像处理于MATLAB上的应用，能很好的处理一些熵，概率等问题-(a)Find the entropy of this source using Matlab (b)Design the Huffman code for this source using Matlab. (c) Randomly generate a source sequence of length 500 symbols drawing the symbols from the true source distribution. Encode the generated sequence using the Huffman code developed in (b). Decode the sequence and compare the decoded and original sequences. (d)Find the efficiency of the code in this case.

[Program doc] LDPC DL : 0: 针对LDPC码在理论和实现两方面分别进行了较深的研究。深入了解了LDPC码编码方法、译码方法以及性能等知识，重点研究了用MATLAB如何构造奇偶校验矩阵、如何编码和如何解码的算法，而且实现了在相同码率、信噪比下LDPC码性能与卷积码性能的对比。-LDPC codes for both theory and implementation were carried out deeper study. In-depth understanding of the LDPC coding method, decoding method and performance of such knowledge, focuses on how to use MATLAB parity check matrix structure, how to encode and decode algorithms how, but also achieved at the same rate, SNR LDPC codes Comparative performance and convolution code performance.
