On Performance of Multiple-domain Diversity in Powerline Communication Networks

In this paper, we theoretically analyze the achievable physical layer performance of multiple-domain diversity mechanism in wireline home networks, where the content is either kept within the same domain or distributed over different domains. We theoretically evaluate the symbol error rate (SER) performance and outage probability of multiple-domain PLC network based on minimum mean square-error (MMSE) combining while taking into consideration the impact of different noise impairments in powerline channel. It has been shown that required signal-to-noise ratio can be reduced while achieving the target performance if the system is properly designed.
