Study on multi-node broadband power line channel modeling
摘要
Abstract
With the wide application of the broadband power line communication technology in AMI system, the most urgent need is to set up a digitization integrated test environment for the carrier communication. The existent testing method is mainly derived from the conditional point-to-point power line channel model. Due to the multi-stage relay routing mechanism in carrier communication, the multi-node channel model is proposed for the link-level and system-level performance testing. Based on the two-port network theory, the multi-node broadband power line channel modelling approach is presented. With this method, the system model is simplified through the sub-network centered by branch node and the mechanism of the correlation between different channels in the low voltage distribution network is analyzed under the classical T-shape network. Through comparing real-measured channel response with theoretical simulation result, it verifies that the proposed method can accurately describe multi-node power line channels and channel correlation, which can offer theoretical support for the system-level testing approach and novel high speed broadband power line communication in the future.关键词
