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

on December 6, 2018 from 5:30 PM to 8:00 PM

Speaker Dr. Liang Zhang, Senior Research Scientist Communications Research Centre, Ottawa - Canada
Topic Info

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.

Speaker Bio

Liang Zhang (M’11-SM’14) received the bachelor’s degree in the department of electronic engineering and information science from the University of Science and Technology of China, Hefei, China, in 1996, and the M.S. and Ph.D. degrees in the department of electrical and computer engineering from the University of Ottawa, Ottawa, Canada, in 1998 and 2002, respectively. Currently, he is a Senior Research Scientist with the Communications Research Centre Canada (CRC), Ottawa, Ontario, Canada. Since joining CRC, he has conducted research on digital communications systems, communications theory development, signal processing algorithms, physical-layer transmission technologies, antenna technologies, cross-layer design, as well as MAC layer resource allocation and scheduling techniques.

Liang Zhang has been deeply involved in the ATSC 3.0 standardization activities on developing the layered-division-multiplexing technology, mixed fixed and mobile broadcast service delivery, mobile service detection, co-channel interference mitigation, integrated access and backhaul. He is currently working on technologies for the convergence of future TV broadcast and 5G broadband systems.

Previously, he was part of WorldDMB technical committee for the standardization of the Enhanced Stream/Packet Mode in DAB system, and the DAB+ system. He has also conducted research activities on detection technologies for 3GPP LTE and IEEE 802.11 systems.

Dr. Zhang is a Senior Member of IEEE and an Associate Editor of the IEEE Transactions on Broadcasting. Dr. Zhang has more than 70 peer-reviewed Journal and conference publications and received multiple Best Paper Awards for his work on the next generation ATSC 3.0 and the 5G broadcasting systems.

 From North County:
Take 5 SOUTH, just past Del Mar, stay in the right two lanes and take Local Bypass–Carmel Mountain Road. Stay right and exit Carmel Mountain Road. At bottom of exit go right. (Beware you can’t turn right on a Red light). Go to Sorrento Valley Road and turn left. Drive about a mile to Sorrento Valley Blvd and go right over railroad tracks. Make immediate left onto Roselle Street. Follow it through the curves to almost the end of the road. ATEC Corporate Center is on the left in a two story Beige building.
From South County:
Take 5 North to Sorrento Valley Road exit. At bottom of off ramp, go right. You will be on Roselle Street. Stay on Roselle through the curves to almost the end of the road. ATEC Corporate Center is on the left in a two story Beige building.

ATEC Corporate Center special meetings are held in the very back of the building on the same side as ATEC Shipping & Receiving area.  Drive into parking lot, park in the back area near dumpster. Entrance to the Training/Meeting room is up the double stair case (with plants, palm trees, etc.) enter door on right.
