Low complexity detection algorithm for Alamouti like STBC for large MIMO systems

This paper presents Alamouti like STBC for large MIMO systems and its low complexity detection using Tabu search. Large MIMO systems are of primary concern in the deployment of 5G. We propose a solution of using Alamouti like STBC for the transmitter design and decoding the received signal using a heuristic based search algorithm named Tabu search. Our results show that low complexity detection technique performs better than decoding techniques like Zero Forcing (ZF) and Minimum Mean Square Error (MMSE) while is comparable to Maximum Likelihood (ML). We consider Rayleigh channel for all the simulations.
