Hands-On Full-Duplex Radio Design

Date/Time: Wednesday, 22 January — 8:00am – 11:50am

Lecturer:  Ken Kolodziej, MIT

Abstract

Full-duplex technology is revolutionizing the wireless world! This system concept is fundamentally different that traditional radios that divide transmission and reception in either time and/or frequency.  Future networks will leverage this emerging technology to improve efficiency and enhance mobile user experiences.  This short course will introduce attendees to the various self-interference cancellation techniques that enable full-duplex operation in wireless systems and will allow them to experiment with their own full-duplex designs through hands-on engineering with real-world hardware/software.

Kolodziej is the editor of the In-Band Full-Duplex Wireless Systems Handbook (Artech House), has been an associate editor of the IEEE Microwave Magazine since 2021, and was a guest editor of the IEEE Transactions on Microwave Theory and Techniques in 2023. He is a senior member of the IEEE and a member of the IEEE MTT-S Wireless Communications (MTT-23) technical committee, and has been a member of the technical program committees of several conferences..

AMD Radio Frequency System on Chip (RFSoC) – Architecture, System Development, and Applications

Date/Time: Wednesday, 22 January — 13:30pm – 17:20pm

Lecturer:  Robert Stewart & Louise Crockett, University of Strathclyde, UK.

Abstract

Systems for radio and wireless instrumentation, particularly in research & development environments, can benefit from the ability to create custom designs easily. However, one of the difficulties is that the ADCs and DACs tend to be separate from the processing platform, requiring a range of skills and potentially some interfacing challenges to solve.

AMD Zynq UltraScale+ RFSoC is a family of devices that combine multiple multi-Gsps RF-ADCs and RF-DACs with processors and Field Programmable Gate Array (FPGA) programmable logic, all on the same chip. These are powerful platforms with various applications including: 5G mobile and other wireless communications systems, radar, measurement and instrumentation, and quantum computing. The reprogrammable features of RFSoC devices can be especially useful where custom functionality, dynamic operation, or future upgrades are required.

This short course will introduce the RFSoC architecture and features, and outline the design process for developing custom systems. In particular, we will highlight how software, hardware, and data converters can be combined to make an integrated system, leveraging the open-source PYNQ (Python productivity for Zynq) project to make the design process easier. The operation of the high speed RF-DACs and RF-DACs will also be reviewed, applying the classical signal processing theory of Nyquist sampling to support RF frequencies up to 5GHz. Finally, we will present some RFSoC-PYNQ examples, discuss potential applications, and highlight support for getting started with this technology.
