Title:
ADAPTIVE EQUALIZER
Document Type and Number:
Japanese Patent JPS6210932
Kind Code:
A
Abstract:
An adaptive equalizer 200 is disclosed which includes a plurality of multiply-accumulate devices 201, 202, 203 and a rotating coefficient register 212. Each multiply-accumulate device 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. The rotating coefficient register successively associates each coefficient in the ensemble with a different multiply-accumulate device. Coefficient update circuitry 213, 230, 214, 216, 215 is also provided which periodically updates the coefficents in the ensemble so as to optimize equalizer performance.
