Space-time coding has been receiving much attention due to its potentials offered by fully exploiting the spatial and temporal diversities of multiple transmit and receive antennas. A differential ...

We consider differential modulation and demodulation in a decode-and-forward (DF) multiple relay system when channel state information (CSI) is unknown to any node. This paper first derives the ...
