A Minimum Bit Error Rate Loading Algorithm for OFDM Systems
一种基于最小误码率的OFDM自适应比特及功率分配算法

An efficient power and bit allocation algorithm is proposed for wireless OFDM systems aiming at minimization of the bit error rate under the constraint of total transmit power and data rate. The algorithm is based on the water-filling approach and adopts a new iterative method to improve its stability. Simulation results show the proposed algorithm has a better performance and a lower computational complexity compared to the previous ones.
