Apparatus and method for equalizing a digital input signal, receiver, base station and mobile device

Abstract

An apparatus for equalizing a digital input signal is provided. The apparatus includes an input node configured to receive the digital input signal. Further, the apparatus includes a plurality of filters coupled in parallel to the input node. The plurality of filters are configured to filter the digital input signal and generate a respective filtered signal. Additionally, the apparatus includes a combiner circuit coupled to the plurality of filters. The combiner circuit is configured to receive the respective filtered signal from the plurality of filters, and to generate an equalized signal by combining the received filtered signals according to a non-linear equalization function.
