The Control Method of Directional Antenna Beams using Genetic Algorithm and Fuzzy Logic System

This paper presents a novel control method that quickly search for the sweet spot of directional antenna beams, and save they for fast speed transmissions in millimeter wave. The proposed method is the Genetic Algorithm and Fuzzy Logic system. Transfer method is using TDD, and it transfers the control data of antenna. We can transfer and receive a large data in millimeter wave bandwidth. Because antenna signal accounts for a few bits, influence on communication performance is little. The Genetic algorithm is used to find the approximate range as a pre-processing function. And the fuzzy logic system is used to find the exact sweet spot. Genetic algorithm operators are used one-point crossover, rank-based selection, bit string mutation and elitism. In the fuzzy logic system, Rule base inference is used the max-min inference procedure. Defuzzification is used the center of gravity computation. The efficiency of the proposed method is verified by means of simulations.
