Abstract (en)

[origin: EP0964555A1] The invention relates to an adaptive CAP receiver, comprising a clock-controlled A/D converter for converting the input signal, digital level control, adaptive controlled receive filtering with two parallel filters and a downstream decider for outputting the reconstructed signal co-ordinates. According to the invention, the digital level control and the adaptive receive filtering processes are decoupled. Either the digital level control setting or the coefficient setting of the receive filtering is active.
