Abstract

To minimize average bit rate error(BER) per orthogonal frequency division multiplexing(OFDM) frame under the constraint of total transmission power and data rate in time-varying channel, iterative algorithm of bit and power allocation aiming at minimum total virtual power(MTVP) in OFDM symbol was designed, and a method of power allocation among OFDM symbols based on MTVP was proposed. Simulation results show that the proposed bi t and power allocation method improves the BER performance as well as calculation speed.
