Technology Showcase Presentations
Rapid FPGA Assembly for GNURadio
Richard Stroop (Virginia Tech & Configurable Computing Laboratory, USA); Peter Athanas (Virginia Tech, USA)
Abstract - Software defined radios have changed the paradigm of slowly designing custom radios, instead allowing designers to quickly iterate designs with a large range of functionality. With the help of environments like GNURadio, a designer can prototype radios with greatly improved productivity. Unfortunately, the playing field is limited by software performance, and there is no way to achieve the range of radio designs possible with actual physical radio hardware. In order for SDRs to become more prevalent in radio prototyping and development, accelerators must be added to speed up the digital signal processing of high-throughput and/or computationally intensive portions. Custom DSPs, GPUs, FPGAs and more and more GPPs have all been added to SDRs to try and speed them up. One difficulty in this is that by adding these accelerators, the "instant gratification" dynamic of the GNURadio is lost. In this paper, an enhanced GNURadio flow is presented that seamlessly augments the GNURadio software-only model with FPGAs, yet preserves the GNURadio dynamics by providing full-custom radio hardware/software structures in seconds.
MIMO/OTA (Over the Air) Controlled Environment Testing
Fanny Mlinarsky (octoScope, USA)
Abstract - Wireless industry is migrating from conducted to over the air (OTA) testing. Modern wireless handsets and smart phones with cellular, 3G/4G, Wi-Fi, Bluetooth and GPS radios cry out for OTA test methods due to a sheer number of connections. Conducted coupling whereby antennas are replaced with cabling is unsuitable for MIMO and beamforming technologies where antennas may be a significant factor influencing device performance. In this demo we will review OTA test methods and metrics being developed at 3GPP and CTIA and will discuss practical approaches to fast and accurate OTA based production testing.
Airblue: A Reconfigurable Wireless Transceiver
Kermin Fleming, Jr (MIT, USA); Arvind (Massachusetts Institute of Technology, USA); Alfred Man Cheuk Ng (Qualcomm Inc, USA); Hari Balakrishnan (Massachusetts Institute of Technology, USA)
Abstract - Over the past few years, researchers have developed many cross-layer wireless protocols to improve the performance of wireless networks. Experimental evaluations of these protocols have been carried out mostly using software-defined radios, which are typically two to three orders of magnitude slower than commodity hardware. FPGA-based platforms provide much better speeds but are quite difficult to modify because of the way high-speed designs are typically implemented. We have developed Airblue, an FPGA-based software radio platform, that is both easy to modify and runs at speeds comparable to commodity hadware and have used it to perform several cross-layer experiments. Airblue is built on top of commercially available components, with a total cost of less than $2500 per transceiver.
Rapid SCA Development for the DSP (Demonstration Proposal)
Toby McClean (PrismTech, United Kingdom)
Abstract - One of the features of evolving SCA Next standard will be the enhanced support for hosting SCA components on specialized processing environments such as DSPs and FPGAs. There are several tools on the market that support the rapid development of SCA resources for the GPP by generating SCA compliant C++ source code. Spectra CX is the first SCA IDE to offer rapid development of SCA resources for the DSP by compiling the design of an SCA resource into optimized C code utilizing a SCA Next compliant lightweight CORBA implementation. This demonstration will show how new features in Spectra CX enable the rapid design, implementation and deployment of an SCA resource targeting TI DSPs. The demonstration will include an SCA assembly where resources executing on the GPP communicate with and send data to the resources executing on the DSP.
SDR Receiver For Amateur Satellites and CUBESAT Ground Station
Carl B. Dietrich (Virginia Tech & Wireless @ Virginia Tech, USA)
Abstract - We propose to demonstrate a Software-Defined Radio (SDR) satellite ground station for the reception of signals from low-earth orbit Cubesats using the Amateur Radio frequencies. This receiver is designed to replace the Commercial Off the Shelf (COTS) radios that are typically used in satellite ground stations. In this document we briefly discuss the construction of the station and the planned demonstration.
Quality Control: Get Continuous Compliance Checking for your SCA Components
Steve Bernier (The Communications Research Centre Canada), James Ezick (Reservoir Labs), François Lévesque (Communications Research Centre), Jonathan Springer (Reservoir Labs)
Abstract - The purpose of quality control is to ensure the greatest number of errors are caught and removed before delivery. Ideally, quality control is embedded in the development process allowing errors to be corrected as early as possible. SCA modeling tools help developers achieve this goal. SCA Architect is a modeling tool that incorporates over one hundred validation rules to ensure developers will create models that will lead to the generation of compliant SCA components. But what happens after the artifacts such as source code and XML domain profiles have been generated? How can developers make sure artifacts are still compliant after they add business logic? This demonstration will show a unique tool called R-Check SCA that can validate modified source code and domain profiles for SCA compliance. It will show how R-Check SCA can be used as a plug-in for SCA Architect to provide continuous quality control after model-based artifacts have been generated. R-Check SCA uses static analysis methods to check for correctness and consistency across SCA project artifacts in any stage of development. The demonstration will describe the development process for creating complete SCA components and show how R-Check SCA can be used to provide third-party validation of several SCA compliance requirements.
Running JTRS SCA applications on Android
Steve Bernier (The Communications Research Centre Canada)
Abstract - CRC and OIS have recently announced support for the Android platform. Mobile platforms are becoming very popular even for public safety and military applications. Adding support for CORBA and the SCA on Android opens a world of new possibilities for developers. This presentation will cover the details of how ORBexpress and the SCARI GT Core Framework can be used on mobile Android platforms and will include a live demonstration. The demonstration will show SCA waveform applications running on different smart phones communicating with commercial public safety handheld AM, FM, and APCO-P25 radios.
