Title
Iterative Multi-Branch Lattice Reduction-Aided Successive Interference Cancellation for Multiuser MIMO Systems
Abstract
In this paper, we propose an iterative detection and decoding (IDD) scheme for the uplink of coded multiuser multiple-input multiple-output (MU-MIMO) systems. The structure of the proposed soft-input soft-output (SISO) iterative (turbo) scheme is based on a multi-branch lattice reduction successive interference cancellation (MB-LR-SIC) strategy that computes in the first iteration a reliable extrinsic information and then feeds it to the decoder. After the first iteration, the soft cancellation minimum mean square error (SC-MMSE) strategy is used to subtract the residual interference. Simulations show that the proposed scheme has an excellent performance as compared to prior art and approach the single user (SU) scenario with only one transmit antenna which is free from interference.
