ROBUST ANALAYSIS FOR UP-LINK DETECTION IN LOW COMPLEX 5G WIRELESS MIMO-OFDM SYSTEM

Abstract

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.
