Patent ID: 7792481

Claim:
A method for interface adaptation of a hardware baseband receiver in satellite communications systems, comprising: adjusting, by an interface adapter that is inserted between a RF front end and correlators of a hardware baseband receiver, a signal representation of, and at least one of a sampling rate, intermediate frequency, and quantization of, a baseband-receiver interface of the RF front end to specifiable values; wherein at least the following registers are provided for the adaptation: SAMPLE_RATE, corresponding to a sampling rate of front-end data; IF_FREQ, corresponding to intermediate frequency of the front end; NEG_IF, set for reflected IF signals; IF_MASK, corresponding to configuration of the word length of the front-end data; COMPLEX_IF, set when the front-end signal is present in complex form in the I/Q representation, 0 in the case of real signals; ONE_COML, set in the case of signals in the one-complement representation; TWO_COML, set in the case of signals in the two-complement representation; and MID_ZERO, set when, in the analog-to-digital converter, 0 represents a value instead of a threshold.
