Abstract

Orthogonal frequency division multiplexing (OFDM) combines the advantage of high achievable rates and relatively easy implementation. In this paper we present an evaluation of the combined use of the turbo codes (TC) and the orthogonal frequency division multiplexing with pilot-aided data in Rayleigh fading channel with compensation the phase error and perfect compensation. The system is called TC-QPSK-OFDM. The simulation results of TC-QPSK-OFDM at three iterations are sufficient to provide good BER performance with phase error and perfect compensation. The gain factor is 7 dB compared with un-coded QPSK-OFDM with perfect compensation at BER 2*10^-4 and 8 dB at 3*10^-4 with phase error compensation. The proposed system can be used in several wireless standard such as 802-11a.
