Research on A Fruit Fly Optimization Algorithm for OFDM Modulation System

the allocation of bit and power in OFDM system is realized by a improved discrete fruit fly optimization algorithm proposed in this paper. Firstly, the swap operator and swap sequence are introduced into the algorithm, which solves that the traditional fruit fly algorithm is only suitable for the optimization of continuous solutions; the fruit fly algorithm is then improved from the search step length and the update strategy; finally, the OFDM system meets the requirements of power minimization and throughput maximization by the algorithm. The simulation results by MATLAB prove that the improved algorithm is superior to traditional algorithms such as Chow.
