Demonstration of timing error detectors (TED) for single carrier systems.
The Webdemo covers the following timing error detectors
- Gardner TED (oversampling)
- Zero-Crossing TED (oversampling, decision directed)
- Mueller-Muller TED (decision directed)
- Modified Mueller-Muller TED (decision directed)
In the following few slides a brief introduction to each one of these TEDs is give before they and their S-curves are compared.
Note that in practice, the output of the TEDs is rescaled to better match with the actual timing error.
For simplicity and the many possible errors this has not been done here.
