Capacity and BER Performance Analysis of Single Cell Massive MIMO with Various Precoding Techniques

Abstract

Abstract

Massive Multi Input Multi Output (MIMO) is one of the promising technologies which will facilitate the 5th generation wireless communication system (5G) in the near future. It also goes by other names such as, large MIMO, hyper MIMO, full-dimension MIMO and ARGOS. In this technology the Base Station is incorporated with a large number of transmitting antennas (e.g., Hundreds, thousands).  A large number of antenna help to focus the energy into smaller regions of space, which results improvement in throughput and radiate energy efficiency of the system. Other benefits include use of inexpensive, low-power components, reduced latency, simplification of MAC layer, etc. Massive MIMO uncovers a new area of research in MIMO technology. One of the challenges of massive MIMO is finding an optimal precoding technique. A suitable precoding technique is essential to exploit the maximum potential of the massive MIMO system as well as to eliminate some limitation (e.g., Pilot contamination). In this paper, we have analyzed the performance of a massive MIMO system in terms of capacity and Bit Error Rate (BER) for different precoding techniques to find an optimal precoding technique. We have compared numerous precoding techniques such as, MMSE, ZF, MRT, RZF and TPE to each other to choose one optimal precoding technique for the massive MIMO system.
