Sparse underwater acoustic channel estimation in colored Gaussian noise [Renkli̇ Gauss gürültülü seyrek sualtı akusti̇k kanalların kestirimi]
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 ...
Nondata-aided joint channel estimation and equalization for OFDM systems in very rapidly varying mobile channels
(IEEE-INST Electrical Electronics Engineers Inc, 2012)
This paper is concerned with the challenging and timely problem of joint channel estimation and equalization for orthogonal frequency division multiplexing (OFDM) systems in the presence of frequency selective and very ...
Channel estimation in underwater cooperative OFDM system with amplify-and-forward relaying
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 ...
