This paper addresses some of the opportunities and the challenges that could arise in the design and analysis of multi-hop systems that utilize cooperation among several intermediate regenerative relays to provide reliable high-quality communication between a source and a destination. This mode of communication can be viewed as a network-embedded distributed, or extended MIMO system. Using the infrastructure provided by the uplink cellular system, we develop and analyze a distributed space-time coding (DSTC) system based on the Alamouti design. We show that with limited feedback from the base station, a DSTC system with two relays, which act as tetherless antennae, is able to induce and collect diversity in a distributed MIMO setup.
