  • Adaptive equalizer with gain controlled initialization
    Patent number: 6804694
    Abstract: Initialization of an adaptive equalizer is controlled by varying a gain applied to an input signal. The input signal may be an alternate mark inversion signal. The gain is applied to the input signal to form an amplified signal. An autocorrelation value of the amplified signal is calculated. The autocorrelation value is compared to a predetermined constant. The gain is adjusted, based on which of the group consisting of the autocorrelation value and the predetermined constant is greater. The gain application, autocorrelation calculation, comparison and gain adjustment are repeated, until the autocorrelation value is sufficiently close to the predetermined constant to satisfy a convergence criterion. The amplified signal is then filtered.
