Abstract

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.

Description

Technical field [0001] The invention relates to a communication receiver device and a communication method. The present invention particularly relates to a Doppler frequency shift recovery communication receiver device and a communication method. Background technique [0002] The frequency shift caused by the relative motion between the transmitter and receiver is called the Doppler effect. In radio communication, Doppler shift may cause the difference between the carrier frequency of the communication signal at the transmitter and receiver. The frequency shift caused by the Doppler effect is proportional to the relative speed between the transmitter and receiver. The change in the relative speed between the transmitter and the receiver causes a change in the offset of the carrier frequency. If not compensated, this frequency shift can reduce communication quality and sometimes even prevent signal reception. [0003] US6532271 discloses the first method in which the Doppler fre...
