A New, Near-0dB PAPR Waveform for mmWave 5G: STORM
 (Watch the video)
Presenter: Doron Ezri, CTO Wi-Fi, Huawei’s Tel-Aviv Research Center

Abstract:
mmWave is considered one of the technological building-blocks of 5G. However, at higher carrier frequencies, PA efficiency and linearity are naturally more challenging. This led the 3GPP to define DFT-Spread-OFDM (which implements a single-carrier waveform) as mandatory, alongside with OFDMA (at least up to 40GHz).

In this talk we will present STORM – a new waveform (based on DFT-Spread-OFDM) which exhibits near 0dB PAPR. In a nutshell, STORM is a superposition of two (specially crafted) single carrier waveforms, where one “corrects” the PAPR of the other. STORM is attractive as it leads to significant link-level gains over DFT-Spread-OFDM and OFDMA (up to 7.4dB) in a variety of scenarios. Moreover, the STORM transceiver is implemented with simple changes to a Vanilla flavored DFT-Spread-OFDM transceiver – so a multimode transceiver (enjoying all worlds – implementing OFDMA, DFT-Spread-OFDM and STORM) is very natural and straight-forward.

Challenges in mmWave Wireless Channel Measurement and Analysis  (Watch the video)
Presenter: Mir Ghoraishi, Project Leader, 5G Testbed and Proof-of-Concept, 5G Innovation Centre, University of Surrey

Abstract:
Emerging millimetre wave technologies impose tough channel sounding requirements. This is because bandwidth is very wide, e.g. more than 1 GHz, the link is normally super directional, e.g. pencil beams by employing large arrays and beamforming techniques, and the blockage can happen easily as movement of medium size objects can have significant effects on the communication link causing fast variations in the channel. On the other hand the radio system, switches and antenna array design and implementation at millimetre wave are complicated and expensive.  In this talk we will present an overview of the specific challenges for millimetre wave channel sounding and data analysis

Gigabit Baseband Modem Technology for 5G mmWave Applications  (Watch the video)
Presenter: Ray McConnell , CTO, Blu Wireless Technology

Abstract:
New radios operating in the Millimetre wave (>30GHz) bands will form an essential part of 5G due to the ability to deliver gigabit datarates with low latency. Both licensed and license free bands have recently been opened by the FCC at 28GHz, 39GHz, 57 – 71GHz and higher frequencies. This is driving the development of a number of wireless systems targeted at consumer and mobile applications – most notably the 802.11ad extension of the WiFi standard marketed as WiGigTM. This is forecast to develop into a mass market measured in billions of devices per annum over the next 5 years. Meanwhile, MSOs are being driven to rollout dense LTE mobile networks to meet the exponentially increasing data demands for their customers. This presentation provides an overview of relevant wireless technologies needed to deliver against these expectations with focus on advanced flexible gigabit wireless baseband modem technology based on a recent modem SoC development based on the HYDRA modem technology from Blu Wireless. Finally, consideration is given on how this modem technology can be applied to a number of 5G use cases.

Presenter: Liam Devlin, CEO, Plextek RFI

Abstract:
Work is now well under way on the design and development of the first mm-wave 5G demonstrator system. The ultimate aim of these systems is to provide a huge increases in the available data-rates for mobile users. A much quoted goal is to have a network capable of providing seemingly infinite capacity and negligible latency. Operation at mm-wave frequencies allows the use of much wider channel bandwidths and facilities achievement of the ambitious data rate targets. This presentation will discuss the likely operating bands and the options and trends for the realisation of the mm-wave components. It will be illustrated with examples of mm-wave components designed by Plextek RFI for deployment in the first mm-wave 5G demonstrator systems

mmWave Measurement Challenges for 5G  (Watch the video)
Presenter: Tim Masson, Application Engineer, Keysight Technologies

Abstract:
Much of the test equipment currently in place for communications systems is limited to a 6GHz carrier frequency and a 160 MHz modulation bandwidth. 5G is breaking these 4G limitations, creating requirements for much wider bandwidths, operating in higher frequency bands. This paper looks at some significant measurement challenges for testing 5G transceivers and subsystems working at millimeter wave frequencies in the 28 – 40GHz and higher frequency bands. (This could say 60GHz – or really anywhere 50 – 110GHz where the techniques are largely similar).

We will study some of these test & measurement challenges in detail, starting with the challenge of generating high quality test signals at mmWave operating frequencies. We need these signals to be available with accurately calibrated power levels, carrying complex baseband modulation with severalGHz bandwidth with good modulation accuracy. Several different generation architectures will be outlined and for each the predominant causes or error will be examined. Techniques for improving modulation accuracy will be described and the concept of traceable signal quality will be introduced. Typical operating performance will be outlined.
