The conventional rateless coded cooperation (RCC) operates in full-duplex and non-orthogonal multiples access channel (MAC) aiming to enlarge outage capacity with multiplexed Raptor code of high complexity. In this paper, we develop a new RCC scheme using rateless code, which operates in the practical half-duplex or orthogonal channel aiming to achieves coding gain in high SNR region with only one...
Relay stations (RSs) are usually used to enhance the signal strength of the mobile stations (MSs) close to the cell boundary. However, the introduction of RSs to the cellular networks increases the interference to the MS served by the base station (BS) under spatial multiplexing mode. In this paper, we propose a method which can cancel the interference through a novel use of dirty paper coding (DPC)...
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...
