Abstract
A receiver is described, the receiver comprising an ABB filter stage, an ADC stage. The ABB filter stage comprises an ABB filter stage input configured to receive an analog baseband, BB, signal and an ABB filter stage output configured to provide a filtered analog BB signal. The ADC stage comprises an ADC stage input configured to receive the filtered analog BB signal and an ADC stage output configured to provide a digital BB signal. The ADC stage comprises an ADC comprising an ADC input configured to receive the filtered analog BB signal or a signal derived therefrom as an ADC input signal, and wherein the ADC is configured to perform an analog-to-digital, A/D, conversion of the ADC input signal to derive the digital BB signal.
Claims18
A receiver, comprising:
- an analog baseband (ABB) filter stage including an ABB filter stage input configured to receive an analog baseband (BB) signal and an ABB filter stage output configured to provide a filtered analog BB signal;
- an analog-to-digital converter (ADC) stage, including:
- an ADC stage input configured to receive the filtered analog BB signal and an ADC stage output configured to provide a digital BB signal;
- and
- an ADC comprising an ADC input configured to receive the filtered analog BB signal or a signal derived therefrom as an ADC input signal, and wherein the ADC is configured to perform an analog-to-digital (A/D) conversion of the ADC input signal to derive the digital BB signal;
- a first feedback path configured to feedback the filtered analog BB signal to the ABB filter stage;
- and
- a second feedback path configured to feedback the digital BB signal to the ABB filter stage, wherein the second feedback path comprises a first feedback digital-to-analog (D/A) converter.
A communication device for a wireless communication system, the communication device comprising a receiver comprising:
- an analog baseband (ABB) filter stage including an ABB filter stage input configured to receive an analog baseband (BB) signal and an ABB filter stage output configured to provide a filtered analog BB signal;
- an analog-to-digital converter (ADC) stage, including:
- an ADC stage input configured to receive the filtered analog BB signal and an ADC stage output configured to provide a digital BB signal;
- and
- an ADC comprising an ADC input configured to receive the filtered analog BB signal or a signal derived therefrom as an ADC input signal, and wherein the ADC is configured to perform an analog-to-digital (A/D) conversion of the ADC input signal to derive the digital BB signal;
- a first feedback path configured to feedback the filtered analog BB signal to the ABB filter stage;
- and
- a second feedback path configured to feedback the digital BB signal to the ABB filter stage, wherein the second feedback path comprises a first feedback digital-to-analog (D/A) converter.
