The Rateless Coding Aided Multi-Hop Scheme Based on Transmit Antenna Selection for Massive Multiple-Input Multiple-Output Systems

摘要

In this paper, we propose a new rateless coding aided multi-hop scheme for the downlink of massive MIMO systems. The rateless coding aided cooperation based on transmit antenna selection is extracted, with the assumption that the transmitters have no channel state information, whichcan adapt to the time-varying wireless channels in the multi-hop communication of massive MIMO systems flexibly. Moreover, the bit error rate (BER) and the symbol error rate (SER) performances of the proposed multi-hop scheme are analyzed over Rayleigh fading channel. The simulation resultsshow that the proposed scheme obtains almost 3 dB gain at the BER of 10?4, compared to the non-cooperation scheme, when quadrature phase shift keying (QPSK) is adopted.
