Orthogonal chirp division multiplexing for coherent optical fiber communications [PDF]
, 2016 In this paper, we propose an orthogonal chirp division multiplexing (OCDM) technique for coherent optical communication. OCDM is the principle of orthogonally multiplexing a group of linear chirped waveforms for high-speed data communication, achieving ...

Comparison of traffic performance of QPSK and 16-QAM modulation techniques for OFDM system
Journal of Telecommunications and Information Technology, 2005 Orthogonal frequency division multiplexing (OFDM) provides better spectral efficiency than frequency division multiplexing (FDM), while maintaining orthogonal relation between carriers; hence traffic is better carried by OFDM than FDM within the same ...
