Suppression of effects of co-channel NTSC interference artifacts upon digital TV receiver adaptive equalizer |
摘要 |
Adaptive equalizers for digital TV receivers in which the filter parameters are adjusted by decision-feedback are followed in cascade by filters for suppressing unwanted demodulation artifacts of NTSC co-channel interference. The decision-feedback signals are derived from the responses of the filters for suppressing unwanted demodulation artifacts of NTSC co-channel interference. This avoids erroneous adjustments of the filter parameters of the adaptive equalizers that results when the decision-feedback signals are accompanied by demodulation artifacts of carrier components of the NTSC co-channel interference.
