Linear expansions for frequency selective channels in OFDM
(Elsevier GMBH, 2006)
Modeling the frequency selective fading channels as random processes, we employ a linear expansion based on the Karhumen-Loeve (KL) series representation involving a complete set of orthogonal deterministic vectors with a ...
On the cyclostationary statistics of ultra-wideband signals in the presence of timing and frequency jitter
(Elsevier GMBH, Urban & Fischer Verlag, 2008)
Cyclostationarity is an inherent characteristic of many man-made communication signals, which, if properly recognized, can be exploited for performing various signal-processing tasks. Determining the cyclostationary ...
Joint channel tracking and symbol detection for OFDM systems with Kalman filtering
(Urban & Fischer Verlag, 2003)
This paper proposes a new joint channel tracking and symbol detection scheme for pilot symbol-assisted OFDM systems in multipath fading. The proposed scheme uses Kalman filters for both channel tracking and subsequent ...
A low-complexity KL expansion-based channel estimator for OFDM systems
(Springer International Publishing, 2005-04-05)
This paper first proposes a computationally efficient, pilot-aided linear minimum mean square error (MMSE) batch channel estimation algorithm for OFDM systems in unknown wireless fading channels. The proposed approach ...
