  • Patent number: 5349607
    Abstract: In one receiver for phase modulated digital signals, bit packet transmitted with known preamble, of the type foreseeing a maximum likelihood estimation circuit for distortion corrections, it is performed the cancellation of isofrequency interfering signals, having the same frequency of the useful signal and the same modulation type as well.This is obtained making an estimation of amplitude (A), phase (.PHI.) and time synchronism (.tau.) parameters of the interfering signal in correspondence of each bit packet and reconstructing the useful signal with a maximum likelihood estimation process employing these parameters (FIG. 1).

  • Patent number: 5297168
    Abstract: In a radio mobile system in which the radio signals are received by at least two antenna, the signals are filtered, weighted and then combined before being sent to an equalizer. The weighting coefficients are calculated as a function of signals corresponding to the power level received by each antenna and signals which is represent the quality of reception of each antenna. Furthermore, an equalizer control signal is generated from the combination of signals, weighted by the weighting coefficients, corresponding to the time response of the transmission channel to a single impulse.
