Abstract: OFDM is widely used as the modulation standard in all Wireless transceiver systems and recently optical transceiver systems due to its inherent advantage over other modulation standards. The main drawback of the OFDM system is it suffers from the phase noise errors. Common Phase Error (CPE) and Inter Carrier Interference are the two main errors that occur in OFDM systems as result of phase induced noise. Several techniques have been proposed to combat the CPE, such as RF pilot carrier based, Digital Pilot Aided (PA) based, MBB based etc. In this paper a framework for evaluating the performance of MBB and PA based method in estimating the CPE and correcting it is proposed. The framework is designed and implemented in MATLAB 15 Software and the BER is computed for both the methods to compare their performance.
