Paper Title:
The Application of M-Ary Quantum Evolutionary Algorithm in Bit and Power Allocation for OFDM System over the Power Line
  Abstract

Adaptive resource allocation in orthogonal frequency division multiplexing (OFDM) systems is a very promising technique to improve spectral efficiency. According to actual transmission behavior of the channel environment over low voltage power line, M-ary Quantum Evolutionary Algorithm (MQEA) is proposed to allocate bit and power on different sub-carrier channel, which maximizes the total data rate of the system in a downlink transmission with a total power and bit-error rate(BER) constraints. Simulation results show that the proposed algorithm achieve a higher data rate.
