摘要

接收天线中的波束切换在频域产生副本，这使得仅使用单个射频就可以实现MIMO解码。利用单射频对MIMO信号进行解调，减轻了MIMO的体积膨胀，是MIMO信号解调的一大亮点。然而，该方案尚未通过试验台进行验证，特别是在4×4 MIMO情况下。本文介绍了采用单射频链和波束开关天线的4×4 MIMO接收机的测试结果。测试结果显示了解码后4×4 MIMO信号的星座和信噪比。采用波束开关方案时，测得的信噪比平均为12.95 dB，最大信噪比为17.85 dB。该方案适用于需要大量天线和射频电路的大规模MIMO系统。

Demodulation of 4×4 MIMO signal using single RF

Beam switching in the receiving antenna generates replicas in frequency domain, which enables MIMO decoding by using just single RF. It is fascinating to demodulate MIMO signals using single RF, which relieves the volume expansion by MIMO. However, this scheme has not been verified through a test-bed especially in 4×4 MIMO case. This paper presents test results of 4×4 MIMO receiver using single RF chain and beam switching antenna. Test results show the constellation and SNR of decoded 4×4 MIMO signal. When beam switching scheme applies, measured SNR was 12.95 dB on average and 17.85 dB at its maximum. This scheme can apply to massive MIMO system which requires quite a number of antennas and RF circuits.
