An Interference Channel with Generalized Feedback (IFC-GF) models a wireless network where the sources can sense the channel activity. The signal overheard from the channel provides information about the activity of the other sources and thus furnishes the basis for cooperation. This two-part paper studies achievable strategies (Part I) and outer bounds (Part II) for the general discrete memoryless...
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 this paper, we propose a cross-layer optimization approach that exploits retransmission diversity in wireless CDMA communications. Conventionally, data packets that are not correctly detected are usually dropped. These dropped packets can be used to help data packet detection. By exploiting all the retransmitted packets, data packets can be correctly detected with higher probability. The proposed...
