Variable Rate Power Line Communication: Balancing Reliability and Speed Through Spreading Codes
Year: 2026
Type: conference-paper
Abstract: One important technology to realize the communication of the intelligent distribution network is the power line communication (PLC) technology. PLC technology uses existing power transmission circuits for communication, which has the advantage of being easy to deploy. However, the power line channel of the PLC system has serious multipath effects and noise interference. These problems cause the current PLC technology to face the problems of high communication bit error rate (BER). This paper proposes a variable rate-based PLC technology that uses spreading codes to spread the transmitted signal to improve the signal-to-noise ratio (SNR) of the transmitted signal; adjusting the length of the spreading code can adjust the communication rate and SNR accordingly, so as to achieve PLCs having variable rate and reliability. Therefore, the variable rate-based PLC technology is expected to realize high-speed and reliable PLCs and serve the communication needs of smart distribution networks.
