Abstract

A digital receiver includes a pre-de-interleaver processing block for receiving a receive signal including reception data units quantized using a quantization rule. The digital receiver additionally includes a controllable compressor for compressing the data units into a compressed representation, a controllable time-de-interleaver being configured for applying a varying interleaving size in data units, and a controller for controlling the controllable processor or the controllable time-de-interleaver. The controller is configured for controlling the compressor or the time-de-interleaver so that a higher interleaving size such as a higher interleaving time or a higher number of data units per second is applied, when a compression in a lower number of bits is active.
