Performance Analysis of Adaptive Mu-Mimo System

Abstract

A large multi-user scalable multi-input multiple-output (MIMO-MU) Wireless Communications systems, reference to the base station (BS) is made is equipped with a very large The number of antennas (users) gain from very high performance due to high Data and spectral efficiency and reliability can be achieved rates. In a multi-user system independent wireless communication (i.i.d.) and a similar distribution camouflage compound (Rayleigh fading) channels allow multiple antennas Users of independent computers (EU) to transfer transmission data stream At the same time, or BS to transmit multiple streams of user data have to be decoded Each UE on the downlink. In this work, the bit error rate (BER) for large beamforming scale of MU-MIMO system with different types of pre-coding and schemes adjusted the signal to noise ratio (SNR) is evaluated. Two Ways to design the composition of the beam and the pre-chosen channel coding for better need performance and SNR considered- of any communications system is High-speed data with greater accuracy and reliability.
