In order to provide a method for interface adaptation of a hardware baseband receiver in satellite communication systems, an interface adapter, as well as a corresponding computer program and a corresponding computer-readable storage medium that provide a flexible interface for a hardware baseband receiver to a RF front end, where the flexible interface allows different RF front ends to be operated on such a hardware baseband receiver, an interface adapter (100) is inserted between a RF front end (102) and the correlators (101) of the hardware baseband receiver (104); the interface adapter (100) adjusting the sampling rate, intermediate frequency, quantization, and/or signal representation of a baseband-receiver interface of the RF front end (102) to specifiable values.
