The Ic-Based Detection Algorithm In The Uplink Large-Scale Mimo System

Based on the fact that the linear detector (LD) is easy to implement and it can collect good diversity in the uplink large-scale multiple-input multiple-output (LSMIMO) system, the existing detection algorithms aim to find iteration ways to approximate the inverse operation in the LD whose complexity is high. In this letter, we propose the interference cancellation (IC) based detection algorithm in the uplink LS-MIMO system. Different from the existing detection algorithms in the uplink LS-MIMO system, the IC scheme is firstly utilized, and it can provide better bit error rate (BER) performance than the linear detector. Moreover, as we divide the channel matrix into two subspaces in our algorithm, the computational complexity of our detection algorithm will be smaller than the existing detection algorithms.
