The performance of a multicell wireless network is often limited by intercell interference. This paper considers the use of common-private message splitting at the transmitter and common-message decoding at the receiver for intercell interference mitigation. For a downlink multicell system with multiple antennas at the base-stations and single antenna at the mobiles, we utilize a heuristic SDP-relaxation-based...
In virtual MIMO technology, distributed single-antenna radio systems cooperate on information transmission and reception as a multiple- antenna MIMO radio system. In this paper, a new virtual MIMO communication scheme and routing protocol are cross layered designed for a wireless sensor network (WSN) to jointly achieve reliability, energy efficiency and delay reduction. The proposed communication...
Synchronization of relay nodes is an important and critical issue in exploiting cooperative diversity in wireless networks. In this paper, two asynchronous cooperative diversity schemes are proposed, namely, distributed delay diversity and asynchronous space-time coded cooperative diversity schemes. In terms of the overall diversity-multiplexing (DM) tradeoff function, we show that the proposed independent...
