Abstract:
1. A multi-frequency band receiver comprising: a first receive path configured to receive and process a first code multiplex signal; a second receive path configured to receive and process a second code multiplex signal, the first receive path or the second receive path comprising an amplifier comprising a variable gain factor; a combiner configured to superpose the first processed code multiplex signal and the second processed code multiplex signal; a code multiplex baseband stage for processing the superposed code multiplex signal to acquire and use a first baseband receive signal and a second baseband receive signal, the first baseband receive signal representing data of the first code multiplex signal, and the second baseband receive signal representing data of the second code multiplex signal; an amplifier controller configured to control the gain factor of the amplifier comprising a variable gain factor so that the first baseband receive signal or the second baseband receive signal comprises a minimum reception quality which can be variably predetermined and is dependent on an operating state of the multi-frequency band receiver; and an operating state controller configured to predetermine a value of the minimum reception quality, which can be variably predetermined and is dependent on the operating state, on the basis of the operating state of the multi-frequency band receiver.
