AI Technical Summary
In mobile ad hoc networks, fixed CP length cannot adapt to dynamic channel changes, resulting in low spectrum efficiency and insufficient anti-interference capability, and lack of an effective distributed CP configuration mechanism.
The node periodically listens to the signals of its neighboring nodes, exchanges channel multipath delay parameters, calculates the neighborhood aggregation delay spread index through distributed negotiation, selects the optimal CP length and broadcasts the configuration to achieve adaptive CP length adjustment.
Improve spectrum efficiency, enhance anti-interference capabilities, adapt to the decentralized nature of self-organizing networks, and achieve autonomous and collaborative CP configuration and synchronous switching.
