On the Study of Network Coded AF Transmission Protocol for Wireless Multiple Access Channels
In this paper, the performance of the network coded amplify-forward cooperative protocol is studied. The use of network coding can suppress the bandwidth resource consumed by relay...

Randomized Isometric Linear-Dispersion Space-Time Block Coding for the DF Relay Channel
This article presents a randomized linear-dispersion space-time block code for decode-andforward synchronous relays. The coding matrices are obtained as a set of columns (or rows)...

Distributed Space-Time-Frequency Block Codes for Multiple-Access-Channel with Relaying
—In this paper, we investigate diversity gain in coding for a 2-user multiple-access-channel (MAC) with cooperating transmitters–the MAC with relaying. We propose a simple dist...

Spectral efficient transmit diversity techniques without cyclic prefix for fading relay channels
Abstract--This paper proposes spectral efficient relayassisted transmit diversity techniques, i.e., space-time and space-frequency block codes (STBC/SFBC), for single carrier frequ...

Diversity Performance of a Practical Non-Coherent Detect-and-Forward Receiver
—We propose a non-coherent receiver for the fixed detect-and-forward relay channel and derive a closed-form tight upper bound on its bit error probability in Rayleigh fading cha...
