Rate-Less Codes Aided Cooperation Based on Antenna Selection in Multi-user Massive MIMO System

Abstract

The design of coded cooperation scheme based on transmit antenna selection has been being a hot topic in wireless communications. The difficulty lies in the fact that plenty of channel codebooks have to be stored both at the transmitter and the receiver in advance for the fixed-rate coded cooperation, due to the dynamic cooperative transmit antennas in Multi-user massive multiple-input multiple-output (MIMO) system. To reduce the complexity, the rate-less codes aided cooperation scheme based on transmit antenna selection is described in this paper. And the bit error rate (BER) and the symbol error rate (SER) performance analyses are also derived. Simulation results show that the proposed scheme achieves much better performance gain compared to non-cooperative scheme.
