Space Frequency Code for Cooperative Communications with both Timing Errors and Carrier Frequency Offsets
Weile Zhang, Hui‐Ming Wang, Qinye Yin, Wenjie Wang · IEICE Transactions on Communications · 2010
In this letter, we propose a simple distributed space-frequency code with both timing errors and multiple carrier frequency offsets (CFO) in asynchronous cooperative communications. By employing both the Alamouti coding approach and the transmit repetition diversity technique, full diversity gain can be achieved by the fast symbol-wise maximum likelihood (ML) decoding at the destination node. Analysis and simulations demonstrate the effectiveness of the proposed method.
