Abstract
Energy efficient multiple-input multiple-output (MIMO) with beamforming is one of the splendid ways to increase throughput in wireless networks. The existing schemes have focused on multi layer for multi-user. However, when multi layers for multi-user is implemented on wireless networks the system performance degrades in term of energy consumption, time and processing. The single layer multi-user downlink transmission method is proposed in this paper to provide multi-user data handling through single layer transmission, to minimize the existing challenges. The MIMO spatial diversity and multiplexing gain abilities are used to transmit multi-user data through a single layer transmission. The minimum mean square error (MMSE) and zero forcing (ZF) equalizers with successive interference canceller are used at the receiver site to extract the appropriate user information. The beneficial outcomes of the proposed strategy are to reduce the beamforming layer processing time and to enhance the multiuser downlink throughput. The proposed scheme is evaluated between proposed beamforming (Pr-BF) and existing beamforming (Ex-BF) transmission with 16 and 64 quadrature amplitude modulation (QAM) techniques like bit error rate (BER) and signal to noise ratio (SNR). Simulation results illustrate that the proposed multi user MIMO scheme has better BER performance and smooth multi-user transmission in single layer.
