  text: Phase-shift modulated full bridge converters suffer from thermal imbalances
    of the inverter switches. The lagging leg switches are subject to larger commutation
    currents compared to those of the leading leg as the transformer current reduces
    in the freewheeling interval. Furthermore, after this interval, the energy in
    the series inductance may not be large enough to achieve zero-voltage switching
    (ZVS) for the leading leg. Both effects result in thermal imbalances. This paper
    analyzes the alternating-asymmetrical phase-shift modulation to achieve balanced
    conduction and switching losses for all four switches while showing that this
    modulation is easily implemented on standard DSPs. The modulation has been implemented
    to LLC converters where experimental measurement results proved its effectiveness
    for LLC converters by reducing the temperature deviation from 6.3 K to only 0.2
    K such that the peak temperature is reduced from 95 °C to 92 °C. The paper also
    proves that the modulation can be utilized to improve the efficiency of LLC converters
    operated at very low gains while simultaneously reducing the junction temperature
    of all four switches compared to the conventional complementary modulation. Finally,
    EMI implications are analyzed, which show that the modulation may be beneficial
    for reducing the common-mode emissions around the operating frequency.

  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'
