Acesso Inicial Utilizando Algoritmos Genéticos para Redes Celulares 5G mmWave

A Genetic Algorithm (GA) is proposed for Initial Access (IA) beamforming schemes based on codebook, considering a system with a large number of transmit antennas in the base statio and a single-antenna user, operating on the millimiter wave band. The efficiency of the proposed GA is investigated and comparisons are realized. Additionally, the effect of several parameters, such as the number of transmit antennas, codebook size and transmission power are investigated. The proposed GA presents a superior performance and, in the case of small parameters, it was possible to show that the GA-based results approach the exhaustiv search results with considerably reduced implementation complexity. In this way, we can say that the proposed GA-based algorihtm is a good candidate for future wireless networks
