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 ... -
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 ... -
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 ... -
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 ... -
On the second-order cyclic statistics of signals in the presence of receiver impairments
(IEEE-INST Electrical Electronics Engineers Inc, 2011-12)Cyclostationary characteristics of communication signals can be exploited for performing various signal processing tasks. Receiver impairments that affect the cyclic statistics of signals may lead to a degradation in the ...
