Massive MIMO Systems Precoder Design Under Various Environments

The day-to-day increased usage of wireless-connected devices like smart phone, tablets, and laptops leads to the increase in data traffic demand in communication. The upcoming generation like 5G- or 6G-based communications system supports to serve large number of users communicating simultaneously for data transfer with less energy consumption-based additional core requirement. The concept of introducing the base station with thousands of antennas and parallel serving of multiple users simultaneously structure is achieved in the promising technologies called massive MIMO system. The system energy efficiency and radiation energy under concentration are made minimized into smaller area; it enhances the massive antennas systems. This paper discusses the performance of massive MIMO system under various precoding techniques like MRT, MMSE, Rayleigh-based ZF channel fading system under complete state and incomplete state in the transmitter in MIMO System. The results address the achievable sum rate and minimized bit error under various scenarios.
