Method and circuit arrangement for determining a sampling time by a clock signal for symbols of a modulation method

摘要

A circuit structure determines symbols (Se) from a digitized signal coupled onto a quadrature signal pair in a modulation process. The digitized signal is converted with a radial component (R) into polar signal coordinates. Assigned to a modulation method in a complex plane, radii with different scan phases regard signal frequency distribution as characteristics of quality. An independent claim is also included for a circuit structure with a switching device for determining a pulsed signal, optionally corresponding to a decision-regenerative sampling control device or with a value for a varied scanning phase.
