  Abstract

In this paper, a closed-form expression of the ergodic channel capacity for a narrow-band time-reversal comm unication scheme is analytically formulated. In the time-reversal communication scenario, a transmitter sends a si gnal and a so-called time-reversal array receives the signal. Then, the received signal is reversed in the time do main and resent to the original transmitter. Here, one transmitter and an antenna array for the time-reversal array are assumed. Since the spacing between the array elements is large, the signals received by each antenna elemen t can be considered independent. For simplicity, the communication channel is assumed stationary, whose properti es are not changed for the time-reversal process. Based on the obtained formulation, the channel capacities for th e time-reversal and the conventional channels are compared.
