A Joint Algorithm Based on Multi-Objective Optimal Power Allocation and Partial-Fixed Interference Alignment

This paper proposes a joint algorithm based on multi-objective optimization of power allocation and partial-fixed interference alignment in order to address the issues of inadequate selection of optimization objectives and slow convergence of interference alignment algorithm in the power allocation strategy. To begin with, three optimization goals throughput, interference leakage, and system power consumption are chosen to create a power allocation model, and then the transmitter pre-coding matrix is adjusted based on the channel state data, so that the receiver matrix does not need to be repeatedly computed to finish the interference alignment. The findings of the experiment demonstrate that the suggested algorithm offers considerable benefits in terms of system throughput, energy efficiency, transmission dependability, and lessening interference leakage.
