Adaptive equaliser for input data signal

摘要

The adaptive equaliser includes several adaptive filter stages (14) connected in series. Each filter filters the input data signal (13), or a partly filtered input signal in response to a respective adaption control signal (11a) and weights it with respect to the magnitude. It transmits a correspondingly equalised data signal, corresponding to the number of data. The frequency domain ratio of the equalised data signal to the input data signal corresponds to an adaptive filter transmission function. An equalising control is coupled to the filter stages, receiving an equalising control signal (9) and transmitting the adaption control signals (11a-11n), with the equalising control signal containing a magnitude corresponding to the equalising transmit function.
