Abstract

In this paper, we extended the conventional space-time block-codes single-carrier frequency-domain equalization (STBC SC-FDE) to distributed STBC SC-FDE for practical implementation of cooperative networks. We proposed a SC-FDE transmission scheme over frequency-selective fading channels for distributed STBC cooperative network with amplify-and-forward relaying. We showed that the order-two spatial diversity gain achieved by this distributed STBC SC-FDE scheme. Linear receiver processing collects full spatial diversity, while the overall receiver complexity remains comparable to that of conventional without-relay-assisted transmissions over frequency-selective channels. Simulation results were also provided to validate the distributed STBC SC-FDE scheme.
