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)...

On linear processing for dual-hop multi-channel relaying
—In this paper, we consider the amplified-and-forward relaying in a multichannel system with linear processing capability at the relay. We propose an analytical approach to stud...

Hamilton cycles in digraphs of unitary matrices
We conjecture new sufficient conditions for a digraph to have a Hamilton cycle. In view of applications, the conjecture is of interest in the areas where unitary matrices are of i...

A Non-differential Distributed Space-Time Coding for Partially-Coherent Cooperative Communication
In a distributed space-time coding scheme, based on the relay channel model, the relay nodes co-operate to linearly process the transmitted signal from the source and forward them ...

Linear programming bounds for unitary space time codes
The linear programming method is applied to the space Un(C) of unitary matrices in order to obtain bounds for codes relative to the diversity sum and the diversity product. Theore...
