Abstract :
Performance of a single input multiple output (SIMO) orthogonal frequency division multiplexing (OFDM) system is analyzed considering the channel characterized by frequency selective and Rayleigh fading environment with maximal ratio combining (MRC) at the receiver. The analysis includes the effect of inter-carrier interference (ICI) due to frequency offset caused by Doppler frequency shift. The result are presented in terms of bit error rate (BER), power penalty, BER-floor for different values of fading, number of subcarriers, symbol duration and different receiving antennas for BPSK and QPSK modulation schemes. It is noticed that the system suffers significantly due to ICI and can be improved by increasing the number of receiving antennas.
