Performance evaluation of SISO OFDM system in the presence of CFO, timing jitter and phase noise for Rayleigh and Rician fading channels

Abstract

In this paper, performance of a single input single output (SISO) OFDM system is analyzed in the combined effect of normalized CFO, phase noise and timing jitter in both Rayleigh and Rician fading channels. Most common parameters for an OFDM based communication system are carrier frequency offset, phase noise, timing jitter and number of subcarrier. The performance of Bit error rate (BER) and Signal to Interference plus noise ratio (SINR) largely depends on them. Accurate predictions of tolerable value of this parameters will help the system to meet the specification and desired design criteria of OFDM related device and system. Also Rician and Rayleigh Fading channels are analyzed to predict the performance of OFDM system in indoor and outdoor. Results are presented in the term of BER, SINR, BER floor and power penalty. Results show that Rician fading channel suffers less penalty and BER loss than Rayleigh fading channel for combined error analysis.
