Abstract

In this paper, a low-complexity linear group precoding algorithm in the exponential correlation channel model is proposed for massive MIMO systems. The proposed precoder consists of two components: The first one minimizes the interferences among neighboring user groups; The second one improves the system performance by utilizing the ELR-SLB technique. Numerical and simulation results show that the proposed precoder has remarkably lower computational complexity than its LC-RBD-LR-ZF counterpart, while its bit error rate (BER) performance is asymptotic to that of the LC-RBD-LR-ZF precoder as the number of groups increases.
