The spatial and time focusing effects of time-reversal technology make it an ideal candidate for the low interference downlink system to relieve the coexistence issues among different wireless communication systems. The transmitting power would be concentrated at the intended receiver and the leakage to unintended receivers would be automatically suppressed. In this paper, a time-reversal based secondary...
Detection fusion rules for censored wireless sensor networks(WSNs) with multi-hop transmission strategy in fading channel are investigated in this paper. The optimal fusion rule is derived under the assumption of Rayleigh fading channel model. However, the optimal fusion rule required the instantaneous channel state information which is difficult to obtain under resource-constrained WSNs, so a sub-optimal...
The multi-path effect makes high speed broadband communications a very challenging task due to the severe inter-symbol interference (ISI). By concentrating energy in both the spatial and temporal domains, time-reversal (TR) transmission technique provides a great potential of low-complexity energy-efficient communications. In this paper, a novel concept of time-reversal division multiple access (TRDMA)...

This paper investigates multi-user scheduling with limited feedback of partial channel state information for MIMO downlink system based on orthonormal random beamforming (ORBF). It already shows that ORBF could reduce feedback information remarkably at the same time the throughput is asymptotically optimal and scale as DPC. However ORBF yields severely degraded performance with low to moderate number...
