Analysis of a Power Line Communication System Over a Non-White Additive Gaussian Noise Channel and Performance Improvement Using Diversity Reception

Free registration required

Executive Summary

Performance improvement of a power line communication system is presented here considering the noise as a cyclostationary non-white Gaussian random process. Performance of a power line communication system is severely deteriorated by fading and multipath effect. The impulsive noise has been considered time variant, has short duration, random occurrence with a high Power Spectral Density (PSD). It causes bit error in the signal. Using Orthogonal Frequency Division Multiplexing (OFDM) technique, the effect of impulsive noise and fading can be improved greatly. An analytic approach is presented to evaluate the performance of a power line communication link in the presence of the above limitations.
