text: 'In this paper we present a novel channel impulse response estimation technique
for block-oriented OFDM transmission based on combining estimators: the estimates
provided by a Kalman filter operating in the time domain and a Wiener filter in
the frequency domain are optimally combined by taking into account their estimated
error covariances. The resulting estimator turns out to be identical to the MAP
estimator of correlated jointly Gaussian mean vectors. Different variants of the
proposed scheme are experimentally investigated in an EEEE 802.11a-like system
setup. They compare favourably with known approaches from the literature resulting
in reduced mean square estimation error and bit error rate. Further, robustness
and complexity issues are discussed'

text: We derive a class of computationally inexpensive linear dimension reduction
criteria by introducing a weighted variant of the well-known K-class Fisher criterion
associated with linear discriminant analysis (LDA). It can be seen that LDA weights
contributions of individual class pairs according to the Euclidean distance of
the respective class means. We generalize upon LDA by introducing a different
weighting function
