Sparse channel estimation for OFDM-based underwater cooperative systems with amplify-and-forward relaying
(IEEE, 2014)
This paper is concerned with a challenging problem of channel estimation for amplify-and-forward cooperative relay based orthogonal frequency division multiplexing (OFDM) systems in the presence of sparse underwater acoustic ...
İşbirlikli haberleşmede birleştirilmiş zaman kayması ve sönümlemeli kanal katsayısı kestirimi
(IEEE, 2013)
In this paper, we investigate joint channel gain and time offset estimation for two different data aided methods in cooperative communication with amplify-and-forward (AF) relaying. First one is the Cascaded Estimation ...
