Power line channel response method and power line channel response device on basis of multi-port electric circuit network

Abstract

The invention provides a power line channel response method and a power line channel response device on the basis of a multi-port electric circuit network. The power line channel response method includes acquiring a port which is one of other ports except for a source port and a destination port; recording an acquired port when a channel response from the source port to the acquired port and a channel response from the acquired port to the destination port are known; repeating the above steps until all ports are acquired; determining a first sub-network; determining a first channel response via the first sub-network; removing the recorded ports and circuits connected with the recorded ports from the multi-port electric circuit network by the aid of the first sub-network to acquire a network; determining a second channel response for each recorded port by the aid of the channel response from the source port to the recorded port and the channel response from the recorded port to the destination port; and synthesizing the first channel response and the various second channel responses to obtain a channel response of the multi-port electric circuit network. The power line channel response method and the power line channel response device have the advantage that the computation complexity for the power line channel response of the multi-port electric circuit network is reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for responding to a power line channel based on a multi-port circuit network. Background technique [0002] Since the existing power line network can be used to realize interconnection in a wide area, the power line carrier communication technology has received more and more attention. The future power line carrier communication system will require greater bandwidth to meet high-speed data transmission. [0003] In broadband communication channels, the inter-symbol interference caused by multipath effects is an important factor that leads to the performance degradation of the power line carrier communication system. Impedance discontinuities in low-voltage distribution networks can cause signal reflection effects and cause multipath effects in power line communications. [0004] Multipath effect is one of the most important characteristics of power lin...
