Sparse channel estimation for OFDM-based underwater cooperative systems with amplify-and-forward relaying
Şenol, Habib; Panayırcı, Erdal; Uysal, Murat (IEEE Computer Society, 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 ... -
Sparse underwater acoustic channel estimation in colored Gaussian noise [Renkli? Gauss gürültülü seyrek sualtı akusti?k kanalların kestirimi]
Erdoğan, Mustafa; Şenol, Habib; Panayırcı, Erdal; Uysal, Murat (IEEE, 2012)Cooperative underwater acoustic communication systems come into prominence in recent years. Since underwater channels are sparse and additive noise entering the system is colored Gaussian noise. Therefore it is very difficult ...
