Modeling of the residential power line communications channel

Placeholder Show Content


Development and deployment of faster and more reliable residential PLC systems has been tempered by the high frequency selectivity and noise levels in the channel. Use of the existing ground conductor for additional dimensions, to mitigate these challenges, requires an accurate and reliable channel model that captures the PLC network's multiconductor nature. In this dissertation, the PLC network is modeled as a multimode MIMO channel. Multiconductor transmission line (MTL) theory is used to model the line segment (with or without symmetry) as a multimode system. The PLC network's components (line segments, bridged taps and panelboard) are represented with chain-parameter matrices, and the chain-parameter matrices cascaded to calculate the end-to-end PLC network response. Use of multiple modes at the transmitter and/or receiver is shown to result in higher data rates. Performance improvements obtained by using: network impedance matching; receiver diversity (SC, EGC, or MRC); and MIMO techniques (SVD precoding and vector beamforming) appear.
