Optical minimum-shift keying with direct detection (MSK/DD)

Michael Ohm, Joachim Speidel

Abstract

This paper presents a new optical Minimum-Shift Keying (MSK) modulation scheme with high spectral efficiency. The transmitter is realized in an Offset-Quaternary Phase-Shift Keying (QPSK) arrangement. The receiver uses a delay & add filter (DAF) and photodiodes for direct detection. An MSK precoder for the transmitter is derived.
