Abstract

This paper deals with the effect of the Doppler spread in a mobile communication system. The Doppler effect in a moving mobile is computed by predicting the mobile velocity via particle filtering, an instance of Sequential Monte Carlo (SMC) filtering. By calculating the Doppler spread in the receiver and adjusting the transmitter in the appropriate frequency, the performance of communication systems, such as Orthogonal frequency division multiplexing (OFDM) which suffer from loss of orthogonality due to frequency offset, can be improved. Moreover, it is shown that, via performance comparison of OFDM between the compensated and un-compensated for Doppler shift cases, a substantial improvement (O(10驴1)) can be achieved in terms of Bit-Error-Rate (BER) for expectedly large values of Signal to Noise Ratio (SNR)
