How to eliminate carrier crosstalk in a multi-module power line carrier PLC?

Eliminating crosstalk between multiple PLC modules using power line carriers requires frequency division multiplexing and spatial isolation. Each module should be assigned a different carrier frequency with an interval greater than 10kHz. Bandpass filters should be used, ensuring each module responds only to its own frequency. In terms of layout, the distance between modules should be greater than 30cm, or metal partitions should be used for isolation. Time division multiple access (TDMA) should be used as the communication protocol to avoid simultaneous transmission. Crosstalk coupling should be analyzed through simulation to optimize frequency allocation. In actual testing, with 10 modules operating simultaneously, the bit error rate should be less than 10^-5. Eliminating crosstalk supports high-density deployment and is suitable for smart homes and building automation.
