AI Technical Summary
In existing technologies, self-interference signals are not fully utilized in full-duplex relay communication, resulting in low energy harvesting efficiency and insufficient power management and joint optimization capabilities, leading to low energy utilization and poor system throughput.
By dividing the communication cycle into sub-intervals of information signals and energy signals, combining the self-circulating energy signals, and employing a discrete battery model and backward recursive dynamic programming, cross-cycle optimization of energy allocation and precoding is achieved. The self-circulating signals are used as the energy source, and storage loss is avoided through proportional allocation.
It improved energy harvesting efficiency, reduced energy fragmentation and waste, enhanced the continuous working capability of relay nodes in energy fluctuation environments, and increased system throughput.
