Effects of Channel Estimation Errors in OFDM-MIMO-based Underwater Communications
Håkegård, Jan Erik; Grythe, Knut Harald (Chapter, 2009)State-of-the-art radio communication systems are in a large extent based on multi-carrier communication (OFDM) and multiple antennas (MIMO). In this paper the performance of such systems adapted to an underwater acoustic ... -
Non-perfect channel estimation in OFDM-MIMO-based underwater communication
Grythe, Knut Harald; Håkegård, Jan Erik (Chapter, 2009)The main focus in this publication is on the mean square error of underwater acoustic channel estimators as function of the delay and Doppler spreads of the channel, and the effect this estimation error has on the bit error ... -
Predicting Near-Time Satellite Signal Attenuation at Ka-band Using Tropospheric Weather
Grythe, Knut Harald; Bråten, Lars Erling; Rønning, Snorre Stavik; Tjelta, Terje (Chapter, 2018)There are satellite communication applications where it is desirable to predict near time (e.g. 2 to 12 h) propagation losses at Ka-band due to hydrometeor precipitation. We present results from a project investigating the ... -
