Abstract :
We propose a coding strategy for wireless relay networks with no channel information based on Cayley differential unitary codes. While satisfying the requirements for differential distributed space-time coding, our scheme furthermore inherits of the advantages of Cayley codes, namely high rate, efficient encoding, and a linearized sphere decoder.
