Abstract

The invention provides a power line communication signal adaptive reconstruction method which can reconstruct and generate a power line communication signal sequence without lost data. The method comprises the steps of: acquiring a power line communication signal sequence and converting the power line communication signal sequence into a signal matrix; according to the signal matrix obtained by conversion, constructing a transformation operator matrix; constructing a measurement matrix; according to the obtained transformation operator matrix and the constructed measurement matrix, iterativelyupdating the signal matrix, until current iteration times are equal to a length of the power line communication signal sequence; and carrying out conversion on the currently obtained signal matrix togenerate the power line communication signal sequence without lost data. The invention relates to the field of communication.

Description

technical field [0001] The invention relates to the communication field, in particular to a power line communication signal adaptive reconstruction method. Background technique [0002] Compared with various wired communication technologies, Power Line Communications (PLC) has the advantages of no need for rewiring and easy networking, and has broad application prospects. The power line communication technology is divided into narrowband power line communication (Narrowband over power line, NPL) and broadband power line communication (Broadband over power line, BPL). Narrowband power line communication refers to the power line carrier communication technology with a bandwidth limited to 3k-500kHz. Including the regulated bandwidth of CENELEC in Europe (3~148.5kHz), the regulated bandwidth of the U.S. Federal Communications Commission (FCC) (9~490kHz), and the regulated bandwidth of the Association of Radio Industries and Businesses (ARIB) in Japan ( 9~450kHz), and China's ...
