How to adapt a power line carrier PLC to a power line noise environment?

Adapting to power line carrier PLCs in noisy power line environments requires dynamic parameter adjustment and enhanced signal processing. Adaptive equalization technology is employed to compensate for channel distortion in real time. Transmit power is dynamically adjusted based on the signal-to-noise ratio, reaching a maximum of 10W. The receiver uses digital filtering algorithms, such as LMS adaptive filtering, to suppress narrowband noise. On the hardware side, an adjustable filter is deployed, with the center frequency following the carrier frequency. Through field testing, noise spectrum recording is performed to optimize algorithm parameters. After adaptation, the communication success rate in noisy environments should be greater than 99%. This adaptation design ensures reliable communication under various power line noise conditions.
