Abstract
Disclosed is a device for generating a transmission pulse, configured to: obtain information about a transmission pulse, wherein the information comprises a pulse shape; generate a plurality of kernel pulses on the basis of the pulse shape; form a transmission pulse based on the plurality of kernel pulses.
Claims11
A device for forming a transmission pulse, in particular an UWB-chip-pulse having a plurality of lobes with different polarity, configured to:
- obtain information about a transmission pulse, wherein the information comprises a pulse shape;
- form a plurality of kernel pulses on the basis of the pulse shape;
- invert at least partly one or more kernel pulses on the basis of the polarity of a lobe of the pulse shape, wherein the inversion of a kernel pulse depends on a minimum and/or a zero-crossing of the pulse shape;
- and/or a minimum of a non-negative pulse formed by integrated kernel pulses;
- adapt a pulse amplitude formed by integrated kernel pulses such that one or more minima are changed from a non-zero value to zero;
- form a transmission pulse based on the plurality of kernel pulses.
