KeywordsCarrier suppressed return to zero, duobinary return to zero, modified duobinary return to zero The simulations for the modulation techniques performance were carried out in OptiSystem 17 software. The modulation techniques researched on are carrier- suppressed return-to-zero (CSRZ), duobinary return-to-zero (DRZ) and modified duobinary return-to-zero (MDRZ). Yankho Alexander Chitungu (m.tech student )Įlectronics and communication engineering department PDM universityĪbstract In this paper the power budgeting of the different modulation techniques is investigated in order to determine which one has the best performance in terms of transmitting power.
