Abstract: A modulo-based ADC implementation is provided and 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.

Abstract: A radio channel may comprise a first component between two devices, and second and third components via the controllable scatterer. First reference signal(s) may be transmitted with the controllable scatterer configured to alter a propagation of signals such that influence of the second and third components of the radio channel is mitigated. Second reference signal(s) may be transmitted with the controllable scatterer configured to alter a propagation of signals such that influence of the second and third components of the radio channel is increased. An estimate of the first component may be determined based on the first reference signal(s) and an estimate of the third component may be determined based on the second reference signal(s) and a pre-computed estimate of the second component.
