  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: In this paper, we experimentally evaluate algorithms for velocity estimation
    of a GSM 900 mobile terminal which are based on the analysis of the statistical
    properties of the fast fading process. It is shown how theses statistics can be
    obtained from the training sequences present in downlink transmission bursts without
    establishing an active connection. Realistic simulations of a GSM channel according
    to the COST 207 channel models have been conducted. These models incorporate effects
    like multipath propagation, fading, cochannel interference and additive noise.
    It is shown that velocity estimation by searching for the maximum slope of the
    power density spectrum of the fast fading performs best.
