研究了无速率空时分组码（RSTBC）在天线失效的大规模多用户MIMO系统中的性能。本文说明了在无线擦除信道上的大规模MIMO传输中，无速率空时码部署的基础，其中分组可能会丢失或在接收机处由于天线元件故障而不可解码。由于在大规模MIMO系统中部署了大量的天线元件，因此总是存在某些天线元件失效的可能性，这可能会显著降低系统性能。结果表明，RSTBC保证了系统的可靠性，即使在这种情况下，故障率为25%。仿真结果证明了该方案的可行性。
This paper studies the performance of rateless space time block code (RSTBC) in massive multiuser MIMO systems with antenna element failure. The paper illustrates the basis for rateless space time codes deployments in massive MIMO transmission over wireless erasure channels, where packets may get lost or are not decodable at the receiver due to antenna element failure. Since a large number of antenna elements are deployed in massive MIMO systems, there is always a possibility of failure of some antenna elements, which may degrade the system performance significantly. The results show that RSTBC guarantees the reliability of the system in such cases even when the failure rate is 25%. Simulation results are provided to demonstrate the feasibility of the proposed scheme.
