i have solution for your query. There is one simulation software called OptSim, in that u find MLSE equalizer for optical QPSK/DQPSK signal. We r in distrubution of this tool... If u r interested u can visit to www.foservice.com Contact 266923280.

well, the papers are as the followings: 1) "Dispersion tolerant 21.4-Gb/s DQPSK using simplified Gaussian Joint-Symbol MLSE" 2) "A 10.7-Gb/s DPSK Receiver with 4000-ps/nm Dispersion Tolerance using a Shortened MZDI and 4-state MLSE"

i got some papers which have done phase modulation and used MLSE receiver. But i didnt get the process how they have done that. Do anyone know about the MLSE equalizer for optical comm. BR// Zaman

Are you sure that you can do phase modulation over a channel that does not relay phase information? Julius

Hi,
I want to do simulation on MLSE equalizer for optical QPSK/DQPSK signal
first then i will go for experiment.
I need Matlab file for that.
I have read some recent papers on that but i dont understand the basic
things of MLSE clearly for optical communication.

Can anyone provide me any resources on MLSE equalizer.

i really appreciate your help.
BR//
