摘　　要：笔者主要研究了MU-OFDM系统中子信道-比特-功率的分配算法,在系统传输速率R、系统误比特率BER一定的情况下,改进了算法以优化系统的发送功率P的分配,使之达到最小,并兼顾用户间的公平性。还对此算法进行MATLAB仿真,通过对结果的对比分析,证实此算法既能保证OFDM的系统性能,又能兼顾用户间的公平性。The author mainly studies the allocation algorithm for channel-bit-power of MU-OFDM systems.With the transmission rate(R)and the bit error rate(BER)under certain circumstances,the improved algorithm optimizes the system in order to reach the minimum system power(P),taking into account the fairness among the users.This paper also simulated the algorithm by MATLAB.Through the analysis of the results,it is proved that the algorithm can guarantee the system performance of OFDM and the fairness between users.
