Analysis of OCDM-PON system based on 16QAM/PPM modulation

Xie Fan

Abstract

this paper studies the phase/quadrature modulation combinations of amplitude modulation, amplitude domain by domaininvestigated 16 QAM modulation format examines PPM modulation format, and 16QAM/PPM combinations from the BER, receiversensitivity, uplink data performance and characteristic of multi-user interference analysis. When applied to the OCDMA-PON ofthe programme, not only saves the cost of pulse Shaper and PPM modulation signal receiver sensitivity significantly improve.
