Abstract

This work serves to demonstrate the use of hybrid QFSK-OFDM (QFSK) and modified BPSK-OFDM (MBPSK) in combating the effects of Narrowband Interference (NBI) and Impulsive noise (IN) as a mixture in Power Line Communication channel. Therefore, in this paper we demonstrate the superiority of modified BPSK-OFDM over QFSK-OFDM and over conventional BPSK-OFDM. The performance analysis of the system is carried out by Matlab simulations whereby the noise models used are the Middleton Class A for IN and NBI models as found in literature. The simulations show modified BPSK-OFDM to have better performance of 5 dB in terms of SNR as compared to QFSK-OFDM and 3 dB better than the conventional BPSK-OFDM.
