OFDM系统的自适应功率和比特分配算法，实现系统资源的自适应分配（2)－原创(adaptive allocation for OFDM system)

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.)
