Cooperative Communication Using Distributed Differential Space-Time Codes
Behrouz Maham, Farshad Lahouti · 2006
In this paper, we propose a distributed differential en/decoding scheme for Alamouti's orthogonal space-time code using in a cooperative system. The relay terminal operates in the decode-and-forward (DF) mode. The proposed scheme does not require the knowledge of the channel state information (CSI) at either user or destination terminals
