Abstract
A reception element receives an analog signal. The received analog signal is converted by a reception chain into a digital signal. Based on the digital signal and a first filtering operation, a correction chain generates a correction digital signal reconstituting dynamic nonlinearities generated by the reception chain. A corrected signal from which the reconstituted dynamic nonlinearities have been removed is then generated by subtracting the correction digital signal from the digital signal.
Claims25
A circuit, comprising:
- a reception chain configured to convert an analog signal into a digital signal;
- a correction chain configured to generate a correction digital signal reconstituting dynamic nonlinearities generated by the reception chain, based on the digital signal and on a first filter;
- and
- circuitry configured to generate a corrected digital signal from which the reconstituted dynamic nonlinearities have been removed by subtracting the correction digital signal from the digital signal.
A method, comprising:
- converting, via a reception chain, an analog signal into a digital signal;
- generating, by a correction chain, a correction signal estimating dynamic nonlinearities generated by the reception chain, based on the digital signal and based on a first digital filter;
- and
- removing the reconstituted dynamic nonlinearities by subtracting the correction signal from the digital signal to generate a corrected digital signal.
