Abstract
Massive MIMO system in the fifth generation can consume a large amount of energy. In this research, the selection of antennas was studied based on several algorithms and a new algorithm was proposed for the selection of antennas. The results showed through a comparison between the approved and proposed methods in the research in terms of capacitance that The proposed algorithm is the closest in terms of capacity to the ideal case, as this method is considered almost ideal for its application in multi-input and multi-output systems to improve performance in the fifth generation, followed by the greedy algorithm and algorithm norm, as it was noted from During the comparison in terms of energy efficiency, it is possible to increase energy efficiency when choosing a certain number of antennas
Highlights
Increasing the antenna push to increase the number of devices associated with antennas, including amplifiers (PA), digital to analog converters (ADC), analog to digital converters (DAC), in transmitting and receiving antennas
We study the performance of different antenna selection algorithms, and we proposed an algorithm that can provide the highest throughput at low processing time
A new method has been proposed for selecting antennas in MIMO wireless systems, which is a method inspired by the Multiple Signal Classification abbreviated (Music), which is the most common technique in practical applications due to the presence of an unknown number of signals, which makes up the channel array
Summary
MIMO) we have antennas (Nt) at the base station and a receiving antenna (Nr) at the user. Data is transmitted from the base station over the Rayleigh channel. Since the number of receiving station antennas is much less than the base station, (Time Division Duple). TDD technology was used, which is one of the techniques in which the same frequency in transmitting and receiving data periodically, the downlink and uplink directions are separated in the time domain because the same frequency band is used and that ( H). H: It represents the product of the number of transmitting and receiving antennas where the channel is y1. The figure: shows the block diagram of the antenna selection process MIMO systems. Where the black pointer antenna indicates the selected active antennas, Otherwise, it refers to the antennas that have not been selected
