Abstract
In this study we will study the effects of Carrier Frequency Offset (CFO) upon Signal to Noise Ratio (SNR) for an OFDM system. We will also present performance analysis of two CFO estimation schemes: time domain Cyclic Prefix (CP) based estimation scheme and frequency domain based Moose scheme, Simulation results show that frequency domain based scheme can achieve better performance in term of Mean Square Error (MSE) than the time domain CP based scheme. Both schemes are analyzed under Doppler fading.
