  text: A measurement method is presented that combines the advantages of the multisine
    measurement technique with a prediction method for peak bending behavior. This
    combination allows the analysis of the dynamic behavior of mechanical structures
    at distinctly reduced measurement durations and has the advantage of reducing
    high excitation impacts on the structure under test.

  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'
