SYSTEM AND METHOD FOR PROVIDING A WIRELESS/POWER-LINE DIVERSITY COMMUNICATIONS CHANNEL

摘要

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.
