Performance comparison of optical 8-ary differential phase-shift keying systems with different electrical decision schemes: Comment

Artikel i vetenskaplig tidskrift, 2006

We summarize three electrical decision schemes that have been proposed for 8-level differential phase-shift keying, briefly discuss their performance and complexity, and comment that two of these schemes have been confused in an earlier comparison in Optics Express. © 2006 Optical Society of America.
