A Hybrid TDMA/CDMA System Based on Filtered Multitone Modulation for Upstream Transmission in HFC Networks

  • Giovanni Cherubini

Abstract

We present a novel hybrid TDMA/CDMA system for upstream transmission in multiple-access networks. The hybrid multiple-access scheme is based on a modulation technique related to orthogonal frequency-division multiplexing, named filtered multitone modulation (FMT). After introducing the principles of FMT modulation, we describe its application to upstream transmission in hybrid fiber/coax networks, and discuss the characteristics of the proposed scheme.
