The demand for data traffic in wireless communication system is increasing incessantly with the immense growth of the wirelessly connected devices (e.g. Smartphones, laptops, tablets, etc.). The future generation wireless communication system (e.g. 5G communication system) will have to deal with some core requirements forserving a large number user simultaneously, upholding high throughput for each user, assuring less energy consumption, etc. Researchers have already started to bring new technologies to light to facilitate the next generation communication system. Massive MIMO is one of these promising technologies which have introduced the concept of using hundreds or thousands of antennas at the base station and serving tens or hundreds of user simultaneously. A massive number of antennas will help to concentrate the radiated energy into smaller region hence will improve the throughput and energy efficiency of the system. In this paper, we have investigated the performance of a massive MIMO system utilizing different precoding techniques (e.g. MMSE, ZF, MRT) under Rayleigh fading channel with both complete and incomplete channel state information at the transmitter (CSIT).
