Abstract
The invention relates to a multi-frequency band receiver comprising a first receiving path, a second receiving path, a combiner, a code multiplex base band stage and an amplifier controller. The first receiving path receives and processes a first code multiplex signal and the second receiving path receives and processes a second code multiplex signal. For this purpose the first receiving path or the second receiving path has an amplifier having a variable amplification factor. The combiner superimposes the first processed code multiplex signal and the second processed code multiplex signal. The code multiplex base band stage processes the superimposed code multiplex signal in order to obtain and use a first base band received signal and a second base band received signal. The first base band received signal represents data of the first code multiplex signal and the second base band received signal represents data of the second code multiplex signal. Furthermore the amplifier controller controls the amplification factor of the amplifier having a variable amplification factor, so that the first base band received signal or the second base band received signal has a minimum reception quality which can be variably predetermined and is dependent on the operating state.
