Broadcast Technology Society Event: Non-Orthogonal-Multiplexing : An Enabling Technology for Next Generation Broadcast and Broadband Multimedia Communications

December 7, 2018 @ 1:30 am - 4:00 am

Non-orthogonal multiplexing (NOM) technology can provide significantly higher transmission capacity than the traditional orthogonal multiplexing (OM) technologies, when delivering multiple services with different quality of service (QoS) requirements. This has been recognized by research communities from both the broadcast industry and the mobile broadband industry.


The NOM technology can find many applications in future broadcast and broadband systems, including the simultaneous delivery of mobile and fixed services, seamless local content insertion, and delivery of mixed unicast-broadcast services in 4G/5G systems. A particular interesting new application scenario of NOM is recently developed to realize more efficient integrated broadcast service and backhaul (ISB) transmission, in both next generation ATSC 3.0 digital broadcast system and for 5G broadcasting system. This concept is directly related to the integrated access and backhaul (IAB) technology currently being studied for 5G NR.


This talk starts with the fundamental capacity benefit of NOM technology over OM technologies from the information theory point of view. Then, the different applications of NOM technology in future broadcast and broadband systems are introduced, including the benefit that NOM offers and the challenges to realize it in practice. General guidelines for achieving feasible implementation of NOM in practical systems are subsequently presented that keeps a low complexity and still achieve most of the NOM benefits.


As the second part of this lecture, the concept of using NOM to implement integrated service and backhaul links is introduced. First, the application of this concept in the next generation ATSC 3.0 is presented focusing on supporting low-power gap-fillers to improve the mobile service coverage performance for highly populated indoor and closed areas (airports, shopping malls, stadiums, etc.). Next, this concept is extended for integrated access and backhaul in 5G framework, where the focus is put on realizing a low-cost MBSFN over the low-power-low-tower broadband networks.
