Blind frequency offset estimation for pulse-shaped signals

摘要

This invention relates to a receiver for detecting an optical signal, comprising a processing chain (DSP) being adapted for
- Receiving an optical signal transmitted via an optical transmission channel;
- Determining an estimation of a chromatic dispersion of said optical transmission channel; and compensating said optical signal for said chromatic dispersion on the basis of said estimation;
- And being further adapted to determine a frequency offset and to compensate said optical signal for said frequency offset before the determination of said estimation of said chromatic dispersion.
