Abstract
In this paper, we study the performance of loss tolerant multiuser large-scale multiple-input multiple-output (LS-MIMO) system with rateless space time block code (RSTBC). Since large number of low-power antenna elements are deployed in LS-MIMO systems, there is always a possibility of transmission losses, which may degrade the system performance significantly. In such cases, packets may get lost or not decodable at the receiver resulting in wireless erasure channels. Hence, RSTBC is introduced in LS-MIMO downlink transmission to tackle this problem. Performance analysis and simulation results are provided to demonstrate the feasibility of the proposed scheme in such cases. It has been shown that RSTBC guarantees the reliability of lossy LS-MIMO system with low overhead and complexity.
