Abstract
The massive multiple-input-multiple-output (MIMO) is a key enabling technology for the 5G cellular communication systems. In massive MIMO (M-MIMO) systems few hundred numbers of antennas are deployed at each base station (BS) to serve a relatively small number of single-antenna terminals with multiuser, providing higher data rate and lower latency. In this paper, an M-MIMO communication system with a large number of BS antennas with zero-forcing beamforming is proposed for the improved spectral efficiency performance of the system. The zero forcing beamforming technique is used to overcome the interference that limits the spectral efficiency of M-MIMO communication systems. The simulation results authenticate the improvement in the spectral efficiency of M-MIMO system. The spectral efficiency value using zero-forcing beamforming is near to the spectral efficiency value with the no-interference scenario.
Highlights
In a few years, several studies have been focused on massive MIMO systems which play an important role in emerging trends in communication networks
In various antennas were attached to an array form to organize the base station and mobile stations of the wireless communication link, in order to manage the signal in appropriate direction to improve the system performance [3]
In millimeter wave bands have high path loss at their operating frequencies which are essential for the high gain and sufficient to signal-to-noise ratio (SNR) at a very low distance [14]
Summary
Several studies have been focused on massive MIMO systems which play an important role in emerging trends in communication networks. In various antennas were attached to an array form to organize the base station and mobile stations of the wireless communication link, in order to manage the signal in appropriate direction to improve the system performance [3]. Transmitter and receiver used the beamforming signal transmission from base station to mobile station with multiple antennas [6]. The millimeter wave communication creates the massive MIMO (multi-input multi-output) system more smarts for the size of the antenna is small but makes a possible a huge number of array antennas in a small region at the BS and massive MIMO can conflict the high path loss and fading of mm-wave channels [9]. The massive MIMO is extensively estimated key enable technology and fundamental component of 5G [10][11]
