Abstract

This paper presents a theoretical performance analysis of downlink (base-to-mobile) OFDM (Orthogonal frequency-division multiplexing) micro-cellular radio communication systems. The model developed in this analysis determines accurate interference analysis which takes into consideration frequency and timing synchronization errors between cochannel cells in a Nakagami/Rayleigh fading scenario. This leads to new, accurate and computationally efficient expressions for average bit error rates and cutoff rates of MQAM-OFDM in a micro-cellular environment. Results obtained are applicable in the investigation of the effect of synchronization errors on the spectral efficiency of OFDM based micro-cellular systems. Whilst the system is more robust against timing jitters resulting from separation distances from the victim receiver, frequency synchronization errors above 10-1 have the potential to create a loss in spectral efficiency of up to 7.5% for 16 QAM.
