摘要： The present disclosure relates to a Full-Duplex (FD) transceiver configured to cope with the problem of Signal-of-Interest (SoI) degradation caused by a Self-Interference (SI), as well as to a method for operating the FD transceiver. This problem is addressed by using a modulo- based analog-to-digital converter (ADC) in the FD transceiver. A digital signal obtained by the modulo-based ADC is a folded and quantized representation of a received analog signal. The SI in the digital signal is estimated based on one or more reference signals. The digital representation of the SoI is obtained based on the digital signal and the estimated SI. By so doing, it is possible to provide efficient SI estimation and cancellation. Moreover, since the SI estimation and cancellation are performed in the digital domain, the state-of-the-art analog SI cancellation and/or isolation techniques are not required at all.

摘要： A modulo-based analog-to-digital conversion, ADC, implementation relating to the field of signal processing is disclosured. The modulo-based ADC implementation disclosed herein involves converting an input analog signal into phases of other M periodic analog reference signals based on one or more transfer functions, wherein M≥2. The phase of each of the M reference signals comprises a folded signal corresponding to the input analog signal that is amplitude-folded to fall within a required amplitude range. This signal-to-phase conversion allows a modulo operation to be implemented over the input analog signal. Further, the M reference signals are used to obtain M discrete-time digital signals which, in turn, are used to obtain a digital representation of the input analog signal.
