Empfänger für ein zelluloses Mobilfunkübertragungssystem.

摘要

A receiver is mounted on an automobile telephone or similar mobile station which is included in a cellular mobile radio communication system. The receiver has a high frequency amplifier (3) for amplifying a received input wave, and a mixer (5,10) for converting the received input wave to an intermediate frequency. The gain of the amplifier (3) or that of the mixer is changed on the basis of the level of the field strength (14) of the received input wave and whether or not the mobile station is communicating with a base station. The receiver enhances the reception sensitivity characteristic at locations where the reception field strength is low or the intermodulation distortion characteristic at locations where the field strength is high and intermodulation distortions occur.
