Transceiver optimization for multi-user multi-antenna two-way relay channels
In this paper, we study a multi-user multi-antenna two-way relay system, where a multi-antenna base station (BS) exchanges uplink and downlink signals with multiple users via a mu...

Virtual Topology Design for OBS Optical Networks
—Burst loss and delay are two main issues in optical hop-count. Network diameter is the hop-count of the shortest burst switching (OBS) networks. In OBS, if the hop-count path be...
