摘要：
Time-reversal (TR) signal processing techniques have been applied to ultrawideband (UWB) wireless communication systems, providing myriad of advantages including: reduced receiver complexity and power consumption, increased system capacity, and enhanced immunity to eavesdropping. In this paper, we introduce three new TR-based techniques for UWB wireless: (i) equalized TR beamforming, (ii) TR beamforming with multiple-signal-classification (MUSIC), and (iii) differential TR. We apply them to multiple-input single-output (MISO) UWB wireless communication systems operating in indoor scenarios. We compare the bit error rate (BER) performances of the proposed techniques with those of conventional beamforming.
