By field Using AND/OR By author
This tool can help you build boolean queries suitable for doing a broad search for different synonyms or spellings of each word. Start via the drop-down below or just start typing in the search field.
{{ row.typeTitle }}: ( )

Since our index often lack the full first name of people it can be difficult to correctly search by author.

Fill in the fields and let us help you build a good query:

If you need to find everything possible, consider only searching by last name.

Use "Starting year" to ignore publications out of year range.

Experimental Investigation of Digital Compensation of DGD for 112 Gb/s PDM-QPSK Clock Recovery

Zibar, Darko; de Oliviera, Julio Cesar R.; Ribeiro, Vitor B.; Paradisi, Alberto; Diniz, Julio C.; Larsen, Knud J.; et al. (1 more)

Proceedings of the European Conference on Optical Communication (ecoc) 2011 — 2011, pp. 1-3

For the first time, the impact of DGD on clock recovery for 112Gb/s PDM-QPSK is experimentally investigated and quantified. We propose and experimentally demonstrate novel digital adaptive timing error detector which is robust to DGD.

be performed in digital domain prior to signal demodulation in order to avoid cycle slips. For the first time, the impact of first order PMD, (DGD), is experimentally investigated and quantified for 112 Gb/s PDM-QPSK signal. We experimentally show that the combined effect of polarization mixing and first order
