Abstract

This paper presents the generation and the performance evaluation of an optical quadrature minimum shift keying (QMSK). The performance of our optical QMSK modulated system is evaluated and compared with those of traditional phase shift keying (PSK) and minimum shift keying (MSK) modulated systems, via simulation, in terms of receiver sensitivity, dispersion tolerance and self-phase modulation (SPM) penalty. The proposed scheme shows that the QMSK format offers a few transmission advantages comparing with than that of the other traditional modulation formats under SPM penalty.
