[0002] In recent years, the dual-mode communication system architecture design (HPLC broadband power line carrier and HRF wireless communication) has achieved deep integration of power line and wireless communication, enabling dynamic selection of communication paths based on channel quality and achieving higher communication reliability and lower latency in complex environments. In wireless communication systems, with the increasing scarcity of spectrum resources and the continuous growth in the number of wireless devices, frequency interference and channel congestion between different devices are becoming increasingly prominent. Especially in high-frequency bands (such as the HRF band), the background noise levels differ between channels. If the background electromagnetic environment of each channel cannot be effectively assessed, it can easily lead to a decline in communication quality and insufficient system anti-interference capability.
