A simple algorithm for detection of timing error of a synchronous, band-limited, BPSK or QPSK data stream is proposed and derivation of the s curve reveals a sinusoidal shape.
Abstract: 
A simple algorithm for detection of timing error of a synchronous, band-limited, BPSK or QPSK data stream is proposed. The algorithm requires only two samples per symbol for its operation. One of the two samples is also used for the symbol decision. Derivation of the s curve reveals a sinusoidal shape.

Impact of optical channel distortions to digital timing recovery in digital coherent transmission systems

Fabian N. Hauske, +3 more
TL;DR: In this paper, the authors investigate the systematic influence of optical polarization effects and chromatic dispersion (CD) on digital timing phase estimation in receivers with coherent demodulation and show that half-Baud differential group delay (DGD) in combination with certain states of polarization (SOP) attenuates the clock tone such that the timing phase can not be estimated.
