Abstract: Massive MIMO technology can effectively improve the spectrum efficiency and reduce the transmission power by increasing the number of antennas at the base station, making it a key technology in 5G mobile communication system. However, with the increase of the number of antennas, the complexity of the uplink signal detection increases significantly, the original detection algorithm cannot be achieved in reality. The Reactive Tabu Search（RTS） algorithm based on machine learning and artificial intelligence has become a hotspot in the industry with the advantage of low complexity. In this paper, RTS signal detection algorithm based on BC-GS （Block Constellations- Gauss Seidel） iterative method is proposed to reduce the computational complexity of initial solution to achieve the original BER performance.
