In this report we show how proper cooperation among radio nodes may provide diversity gain, also for single antenna systems. We consider first the connectivity of a wireless network and show how it can benefit from cooperation. Then, we consider some specific forms of cooperations, based on distributed space-time coding, in both single and multi-user contexts. Finally, we pay a special attention to the case where the final destination has a multi-antenna receiver. In such a case, we may establish a virtual MIMO link between the relays and the final destination, which makes possible to benefit also from the MIMO spatial multiplexing gain.
