摘要：

This paper analyzes the effect of distributed time-reversal (DTR) transmission scheme on the signal-to-noise ratio (SNR) at its intended and unintended receivers. By focusing the temporal and spatial signal energy on the intended receiver, DTR can effectively maintain a satisfactory SNR level while lowering received signal level at passive eavesdroppers or unintended co-channel users. The DTR performance is analyzed in terms of a SNR gap between the desired and unintended receivers. The SNR gain of DTR is also analyzed over traditional distributed direct transmission and several cooperative beamforming transmission schemes without time-reversal. Numerical results demonstrate the performance improvement of the time-reversal transmission and the validity of our analytical results.
