Abstract :
A linear pre-coding scheme named LR-BD-ZF (Lattice Reduction-Block Diagonalization-Zero forcing) pre-coding scheme is proposed for downlink in multi-user D-MIMO system with access point (AP) antenna selection is designed in this paper. The perfect channel state information (CSI) at both the transmitters and receivers is assumed. The average symbol error rate (SER) of the LR-BD-ZF algorithm presented in D-MIMO system with antenna selection is inspected through Monte Carlo simulation. The performance of the BD-ZF and LR-BD-ZF scheme in centralized MIMO (C-MIMO) system are also given to compare with that in D-MIMO system. Simulation results show that LR-BD-ZF scheme in D-MIMO system with antenna selection outperforms other schemes.
