Performance analysis of an OFDM system in the presence of Carrier Frequency Offset, phase noise and timing jitter over rayleigh fading channels

摘要

A theoretical analysis for evaluating the performance of an Orthogonal Frequency Division Multiplexing (OFDM) under the combined influence of Carrier Frequency Offset (CFO), phase noise and timing jitter over rayleigh fading channels is presented. An exact closed form expression for the Signal-to-Interference plus Noise Ratio (SINR) is derived and the combined effects of these synchronization impairments are exhibited by the Bit Error Rate (BER) performances of a BPSK-OFDM system over rayleigh fading channels. Results show that OFDM system suffers significant SINR penalty due to CFO and jitter, however, the effect of phase noise is the dominant one.
