Multipath Channel Model for MIMO-Based Broadband Power Line Communications

摘要

Broadband power line communication (BPLC) is a promising medium for network access technology by which broadband services can be offered, such as smart grid, broadband Internet access, digital entertainment, and home networking services. This paper presents a modified multipath channel model for multiple-input multiple-output (MIMO) systems and analyzes the channel capacity and bit-error-rate performance of MIMO orthogonal frequency division multiplexing (MIMO-OFDM) based BPLC over that channel model. The widely-used single-input single-output (SISO) channel model (also called Zimmermann's model) is extended to the MIMO channel model considering coupling effects among conductors.
