Receiver of a mobile communication device

摘要

A mobile communication device receiver for receiving a communication signal of a base station via a carrier includes a filter, a scanner and a first controller. The scanner is configured to scan a frequency range in order to determine a spectral distribution of interference within and/or adjacent to the carrier. The first controller is configured to adapt a passband characteristic of the filter based on the spectral distribution.

1. A mobile communication device receiver for receiving a communication signal of a base station via a carrier, the receiver comprising:
a first filter; a scanner configured to scan a frequency range in order to determine a spectral distribution of interferences adjacent to the carrier and configured to discover a plurality of assigned channels within the frequency range based on the spectral distribution; a first controller configured to adapt an initial passband characteristic of the first filter based on the spectral distribution in order to reduce interferences and provide control data to control a transmit power of the communication signal of the base station, the control data is based on a received signal quality of the communication signal; a first receiving unit for receiving a first frequency band and a second receiving unit for receiving a second frequency band, wherein the scanner is part of the first receiving unit; a notch filter connected to the first filter; and wherein the first controller is configured to further change the passband characteristic of the first filter according to alternative settings of the first filter and to intermittently try other passband characteristics of the first filter that lead to better quality of the communication signal based on the received signal quality of the communication signal and knowledge of the spectral distribution, and wherein the alternative settings are independent of the transmit power.
