Keywords: OFDMA, interference, pilot pattern

Abstract:
This paper presents a systematic approach for analyzing the bit error probability of a coded orthogonal frequency-division multiple access (OFDMA) system in multi-user channels. A comparative analysis with conventional pilot patterns, the overlapped pilot pattern and the interlaced pilot pattern, is developed. Simulation results show that the interlaced pilot pattern is more sensitive to the effect of interference, but also it outperforms the overlapped pilot pattern with serious interference scenarios.
