Abstract	The distributed MIMO (D-MIMO) antenna technique is the most promising architecture for the next generation (5G) of mobile communication system. In this paper, a low complexity downlink group pre-coding scheme is proposed for multimedia broadcast multicast services in D-MIMO system with antenna selection in remote antenna units (RAUs). The ideal channel state information (CSI) is assumed to know at both transmitters and receivers. In order to evaluate the performance of the group pre-coding, the average symbol error rate (SER) of the BD-ZF (Block Diagonalization - Zero forcing) and BD-MMSE (Block Diagonalization - Minimum Mean Square Error) algorithm with group pre-coding and conventional pre-coding in D-MIMO are represented through Monte Carlo simulation. The simulation results and the complexity analysis show that the proposed pre-coding scheme achieves comparable SER performance as the conventional scheme with much lower complexity.
