Adaptive equalizer utilizing a plurality of multiplier-accumulator devices |
摘要 |
Each multiply-accumulate device, in an adaptive equalizer, multiplies each input signal sample by an associated coefficient in an ensemble, stores the result and periodically outputs the accumulated results as the equalized input signal. A rotating coefficient register in the adaptive equalizer successively associates each coefficient in the ensemble with a different multiply-accumulate device. Coefficient update circuitry is also provided which periodically updates the coefficients in the ensemble so as to optimize equalizer performance.
