System-level implications of 802.11 Transmit Beamforng; Swaroop Venkatesh, Director, Systemims Architecture, CSR
The talk provides an overview of 802.11 transmit beamforming technology, followed by an outline of ts impact on the design of 802.11 PHY and MAC layers.
Potential of in-band full duplexing for future wireless systems; Alain Mourad, Wireless Specialist, InterDigital Europe Ltd
Recent advances in self-interference cancellation have opened the door for in-band full duplexing to become a real disruptive technology candidate for future wireless systems. Not only the technology promises up to 2x link spectral efficiency compared to half-duplex TDD and FDD, it also offers multiple other benefits such as reduced air interface latency, improved MAC efficiency, UL/DL decoupling, better trunking efficiency and spectrum sharing. Although significant progress has been made recently for the technology development, there is still a number of challenges that need to be tackled before the technology graduates for adoption in the forthcoming next generation wireless standards (e.g. 5G). This talk will give an introduction to the in-band full duplexing and highlight its potential benefits and challenges for future wireless systems.
Challenges for Power Amplifier Testing with Envelope Tracking - concepts, pit falls, state of the art and trends; Rainer Lenz, Product Manager, Rohde & Schwarz
Mobile devices have become an important tool in our everyday life. We want to use them everywhere and all the time, unfortunately operation time is limited by battery capacity. During the recent years, mobile devices have made more and more use of all broadband access technologies which tend to consume a lot of battery capacity. In order to offer longer operation times, energy saving techniques have drawn the attention of all major chipset manufacturers. One of the key technologies is envelope tracking. This talk will have a look at the basic concepts of envelope tracking and will focus on the challenges which evolve once the design needs to be tested against its specifications - starting from required performance of the measurement equipment throughout the concepts for measuring all the required parameters of power amplifiers with Envelope Tracking Technology. A brief outlook will be given on what might be required in the future to keep pace with the latest trends in the wireless community.
Coffee/Tea & Networking
Envelope Tracking – fuel injection for the RF Front End; Jeremy Hendy, VP Marketing, Nujira
The presentation will introduce ET technology, explain how it overcomes the energy efficiency penalty introduced when transmitting advanced high data-rate waveforms with high PAPR, how it extends to MIMO systems, and how ET can ultimately enable single-chip CMOS integration.
Programmable Wideband PA with Digital Pre-Distortion for High Efficiency; Chris Clifton, Chief Technology Officer & Technology Office Director, Sony SES
We will be discussing a wideband PA (700-3800MHz) PA which can be programmed digitally to meet the requirements for software defined radio architectures. A number of approaches for improving efficiency over the whole operating region will be presented and discussed together with the use of simulation techniques.
Digital Pre-distortion – Transmitter System Engineering and Optimisation; Richard Hewitt, Co-founder and CTO, Systems4Silicon
Digital Pre-distortion (DPD) has been widely researched, however the papers don’t contain the whole story or how to design a practical system. This talk will unearth some of the key engineering decisions that face today’s transmitter system engineer when incorporating DPD and the challenges for DPD as transmit bandwidths increase.
