Agenda:

• "GNU Radio Update" (Martin Braun (https://twitter.com/braun_noise))

Martin is a long-time contributor to the GNU Radio project and the GNURadio community manager. Most of the stuff he touches is SDR-related,and his day job is writing software for Ettus Research, where he's spenta lot of time on RFNoC among other things.

• "A Hands-On Introduction to SDR with GNU Radio & USRP" (Neel Pandeya)

We begin a series of hands-on introductory SDR tutorials using USRP hardware and GNU Radio software on the Linux platform. In this first instalment, we review SDR concepts, explore the USRP hardware, walk through the installation of UHD and GNU Radio on an Ubuntu system, and construct and run a few basic flowgraphs to get familiar with GNU Radio.

Bring your laptop and SDR to follow along!

First instalment of a new tutorial series!

In an effort to cater to all skill levels, we'll be running tutorials so everyone can get up to speed with the basics, and new tips and tricks. The goal is for everyone to enjoy SDR regardless of experience/hardware/software/etc...

• "Interrogating Passive, Wireless SAW RFID Sensors with the USRP" (James ‘Trip’ Humphries)

Passive, wireless sensor design typically dictates many strict performance requirements for the sensor interrogation system in terms of bandwidth, output power, and data capture rate. In the past, this implied that a custom interrogator design would need to be implemented, requiring considerable time and effort as well as being unable to adapt to new sensor requirements. This proves to be particularly challenging in a research environment where sensor specifications may change rapidly. Recent advances in commercial-off-the-shelf (COTS) software defined radio (SDR) platforms have enabled rapid interrogator development while being able to meet the strict requirements of passive, wireless RFID sensor tags.At the University of Central Florida, we have utilized the universal software radio peripheral (USRP) B200, from Ettus Research, to implement a pulsed interrogation system for wideband, wireless surface acoustic wave (SAW) RFID sensors. In this talk, we will discuss the implemented SDR system with consideration given to FPGA modifications, external RF component integration, and post-processing. The system operates at 915MHz with 56MHz bandwidth and has output power of greater than +20dBm. A demonstration of the system will also be given with wireless SAW temperature sensors.
