This paper proposes a novel cooperative diversity protocol for wireless networks, called hybrid amplify-or-decode and forward (HADF) protocol. The new protocol selects amplify-and-forward or decode-and-forward transmission in the relay terminal according to the inter-user channel situation, which is efficient in the sense that it achieves full diversity. The performance of HADF protocol is analyzed...
In this correspondence, a central Wishart multiple input multiple-output (MIMO) K-block fading channel with an information outage probability constraint is studied. Under this block-limited channel condition, we aim to minimize the transmit power required for attaining a given outage probability based on the statistical channel information at the transmitter (SCIT). Using Gaussian approximation to...
