Abstract :
The focus of this paper is on the performance of an orthogonal frequency division multiplexing (OFDM) transmission system considering the combined influence of receiver noise, Rayleigh fading and the timing error due to imperfect slot synchronization at the receiver. Performance results are presented in terms of BER, BER improvement and BER-floor in presence of inter-channel interference (ICI) and inter-symbol interference (ISI) and additive white Gaussian noise for single input multiple output(SIMO) OFDM system using maximal ratio combining (MRC) technique. The results show that there is a significant degradation in system BER due to timing error but can be improved by applying diversity at the receiver.
