A COMMUNICATION RECEIVER DEVICE AND COMMUNICATION METHOD

摘要

The invention relates to a communication receiver device (100) for receiving at least one input signal having an input signal frequency spectrum. The communication receiver device (100) comprises a decomposer (101) configured to decompose the input signal into a plurality of sub-signals, wherein the plurality of sub-signals are allocated to a plurality of frequency bands covering the input signal frequency spectrum, a detector (103) configured to detect whether a frequency band of the plurality of frequency bands is active by determining whether an activity indicator associated with the sub-signal of the frequency band is larger than an activity threshold value, and a combiner (105) configured to combine the sub-signal of a first active frequency band with the sub-signal of a second active frequency band to obtain an output signal, wherein the first active frequency band and the second active frequency band are neighboring frequency bands.
