Abstract
A system and method is presented where a low-IF architecture can be used to allow existing wireless standards to be used for joint wireless/power-line channel transmission in the provision of diversity communications channels. Diversity combining of wireless and power-line channels can be employed, wherein the input noise to the maximum-likelihood detector can be Class A-distributed. For uncoded BPSK, the BER can be a function of PLC impulsiveness and can improve wireless-only BER by orders of magnitude when PLC SNR >10 dB. The error performance can be equivalent to BER of the static PLC channel for low wireless SNR and can improve with a slope of −1 at high wireless SNRs. The inflection point between these two regions can occur at approximately 0 dB when PLC noise is Gaussian, and increases above 20 dB as the noise becomes more impulsive.
