说明：  OFDM通信系统的仿真代码，可用作数字通信的分析参考(The simulation code of OFDM communication system can be used as analysis reference of digital communication.)

详细介绍了ldpc编码以及如何在matlab的simulink 上实现(ldpc matlab simulink)

OFDM 自适应算法能够根据信道的状况进行比特和功率的分配，能够有效的降低误码率.本程序综合了迭代注水算法，CHOW算法，FISHER算法，H-H算法，以及自己改进的迭代注水算法程序，并进行了对比，改进的算法在有效性与迭代注水算法基本相近，但复杂度和实际应用性都更强，值得参考。(OFDM adaptive algorithm make the bit and power allocation according to the status of the channel .It can effectively reduce the error rate.This program combines iterative algorithm, water injection CHOW algorithm, FISHER algorithm, the algorithm of H- H,as well as their improved iterative allocation algorithm procedures.And has carried on the contrast, the improved algorithm in effectiveness and iterative allocation algorithm basic similar, but the complexity and practical applications were stronger with worthy of reference.)
