This paper studies the performance limits of two-way relay channel (TWRC) at finite signal-to-noise ratio (SNR) in Rayleigh fading environment. A two-phase decode-and-forward (DF) protocol is considered. We first derive closed-form expressions for both outage probability and diversity-multiplexing tradeoff (DMT). Our results are general and suitable for any time sharing and any rate allocation in...
When it comes to space communication networks, there are many different kinds of space vehicles that need to communicate with each other, in space as well as with ground terminals and air borne platform. Example: Geosynchronous Earth orbit (GEO), Low Earth Orbit (LEO) satellites and UAVs. There is an ever growing demand for higher data rates and minimal redundancy, with satellites and various space...
In this letter, the outage probabilities of selection relaying protocols are analyzed and compared for cooperative wireless networks. It is assumed that both source and relay use equal allocated time in transmission. Depending on the quality of the source-relay channel, the relay may choose either Decode-and-Forward (DF), Amplify-and-Forward (AF), or Direct-Transmission (DT) to forward signals. It...
In cooperative networks, some of the users in neighborhood of the source relay the source information, in order to combat the effects of multipath fading. Recent investigations, on multirelay amplify-and-forward cooperative networks, have shown that a significant performance improvement will be obtained, if the phase information of the channel between relays and destination are feedback to the relays...
