Abstract

A digital arrangement for selecting a channel coefficient and DC estimate comprises a demultiplexer receiving a digital input signal splitting the digital input signal into a first and second signal, a first joint detection unit receiving the first signal generating a first channel coefficient and DC estimate, a second joint detection unit receiving the second signal generating a second channel coefficient and DC estimate, a first and second error determination unit receiving the first and second channel coefficients and DC estimates, respectively for generating a first and second error signal, a decision unit receiving the first and second error signals generating a control signal, and a selection unit controlled by the control signal for selecting the first or second channel coefficient and DC estimate.
