Efficient and Low Complex Uplink Detection for 5G Massive MIMO Systems

Massive Multiple Input Multiple Output is most promising technology that has been proposed in recent years, and it has been considered a technology to fulfill the requirement of fifth generation network. Even though this technology has many advantages, it must surpass certain challenges as well, and one of the major challenge is signal detection at the base station which becomes more complex with an increased number of antennas. Conventional methods that are used in MIMO detection are computationally very complex and inefficient to use in Massive MIMO system. So, there is a need for suitable detection method for these systems to have good bit error rate performance with lower complexity. In this paper, we propose a more efficient and computationally less complex algorithm for detection of Massive MIMO systems. Results through MATLAB simulations show that our proposed method provides a good tradeoff between computational complexity and BER performance and it is efficient for detection of Massive MIMO systems.
