Abstract :
The simultaneous use of wireless and power line communications (PLC) channels provides a convenient method for increasing the coverage and throughput of indoor networks. In this paper, we compare coding diversity and modulation diversity schemes that both utilize parallel wireless and PLC links. The signal to noise ratio (SNR) values used in this analysis are determined by conducting a series of average link gain measurements in an office environment. Measurement results show that both wireless and PLC SNRs have a wide range, but neither type of media is guaranteed to dominate performance for a given link. The empirical SNR values are used in a Monte Carlo simulation to evaluate the possible throughput advantages of coding and modulation wireless-PLC media diversity.
