Adaptive pulse shaping filter based on interference detection

摘要

A communication device (80) used in a first communication system under a frequency sharing environment where the first communication system and a second communication system establish communications within the same frequency band is disclosed. The communication device comprises a detector (87) for detecting an interfering signal from the second communication system; and a determiner (88) for determining transfer characteristics of a shaping filter (82) according to a result of the detection, the shaping filter being used for a desired signal of the first communication system.
