Title: Programming Cognitive Radio using Sora
Presenters: Kun Tan, Jiansong Zhang, and Paul Wang, Microsoft Research Asia

Cognitive radio and dynamic spectrum access (DSA) will redefine the wireless networking. Enabling this new wireless paradigm requires a powerful and flexible wideband software radio platform. To facilitate the implementation and evaluation of new DSA technologies, Microsoft Research Asia has developed a high-speed software radio platform, called Sora. Sora fully utilizes the capability of state-of-the-art multi-core CPU and high-speed PC bus, and is highly capable to implement and experiment existing broadband wireless technologies, like WiFi and LTE.

In this tutorial, we will first introduce the architecture and basic operations of Sora. Then, we will dive into the Sora programming model and how to use Sora to implement a spectrum agile radio system. The tutorial is also featured with a hands-on session. The attendees can experiment on the real Sora system and use the tools discussed in the lecture to rapidly develop a DSA communication system.

More background information on the Sora platform can be found on MSRA site ( and Sora forum (

Sora is publicly available for academic research. The order information can be found here (

Title: Spectrum Consumption Modeling and Model-Based Spectrum Management
Presenters: John Stine and Sam Schmitz, MITRE

Model-Based Spectrum Management (MBSM) is spectrum management based on the creation and exchange of spectrum consumption models (SCMs).  SCMs define the boundaries of spectrum use so that the compatibility of uses can be arbitrated objectively.  SCM are machine readable and are complemented with algorithms that can be used with the models to compute compatibility, to optimize spectrum assignments, and to find reuse opportunities.  SCM can enhance spectrum management and reuse in several ways:

In regulation, SCM can be used to define a user’s spectrum usage rights.

In commerce, SCMs are a means to capture the quanta of spectrum that are traded.

In technology, SCMs can be used to convey spectrum assignments and spectrum policy to RF systems.

In operations, SCMs can enable very dynamic and flexible management thus increasing spectrum reuse.

These combined capabilities make SCMs a means to enable dynamic spectrum sharing among government and commercial users.  Due to the great promise of this approach to spectrum management especially to enable sharing, there is a standardization effort underway within the IEEE Dynamic Spectrum Access Networks Standards Committee (DySPAN SC) 1900.5 workgroup.  The objective of the tutorial is to familiarize students with the modeling and algorithms so that they can exploit these concepts in their work and research and can contribute to their further development and the standardization effort.

The tutorial will provide an overview of MBSM and the use of SCMs to resolve many of the harder problems of DSA.  It will describe the technical details of the modeling constructs and describe how these constructs are used to model system use of spectrum in both technical and operational contexts.  It will describe the computations required for computing the compatibility of systems based on their models and provide an introduction to the algorithms being developed to perform this and other spectrum management tasks.


Title:  Hands-on Introduction to USRP Software Defined Radio using GNU Radio and LabVIEW for Whitespace and Rapid Algorithm Prototyping
Presenters: John Malsbury (Ettus Research) and Erik Luther (National Instruments)

The USRP(TM) Universal Software Radio Peripheral is a re-configurable software-defined radio platform that has been adopted for many research applications including whitespace research, cognitive radio, and dynamic spectrum access. The USRP product family is supported by a comprehensive software ecosystem that includes GNU Radio, LabVIEW, and other SCA-based and technical computing frameworks. The availability of these tools, and widespread adoption in academia and industry, makes the USRP platform ideal for researchers and engineers looking to rapidly prototype and prove novel concepts.

This tutorial covers the usage of USRP with two of these tools, GNU Radio and LabVIEW.  It begins with a brief introduction to the basic architecture of the USRP platform. After establishing an understanding of the hardware, the presenters will demonstrate GNU Radio and LabVIEW as it applies to the rapid prototyping of whitespace and cognitive radio systems. Using GNU radio we cover advanced USRP features, PHY/MAC layer implementation, and signal detection. Using LabVIEW we first introduce the graphical programming environment and the use of m-file scripts in MathScript RT to rapidly design aspects of a cognitive radio testbed.  Discussed applications of the platforms will include spectrum monitoring, beam forming, localization, and prototyping of cognitive radio architectures. All attendees will have access to source code after the tutorial so they can continue to experiment and pioneer new whitespace and cognitive radio concepts.

Title: TV White Space Standardization Activities: From the Regulation, Technology, Application and Certification Perspective
Presenters: Chin-Sean Sum, Zhou Lan, Hiroshi Harada, NICT Japan

TV white space communications is a timely technology providing solutions to the growing number of bandwidth-hungry applications in the spectrum-scarce environment. The emerging of TV white space communications involves beyond just the technological development. In particular, standardizations, regulations, potential applications and product certification are essential elements playing significant roles in defining the entire industry. The interaction among these elements forms an industrial ecosystem that fuels the engine towards revolutionizing user experience on broadband and seamless connectivity through dynamic spectrum access.

This tutorial covers the panoramic landscape of the international standardization activities related to wireless communication systems operating in the TV white space. The latest development in these standardization activities from the perspectives of regulations, technical specifications, application scenarios and product certification program are presented. Specifically, this tutorial intends to provide insights of the power dynamics in standardization and regulatory activities, the realistic modeling of practical use case applications, the certification programs for developed products, and ultimately, their respective places in the big picture and their relationship with each other.

Title: Spectrum Sharing using Geolocation Databases
Presenters: Peter Stanforth and Jeffrey Schmidt, Spectrum Bridge

Over the past few years there has been a significant investment in the concept of a database for managing the sharing of TV White Space, the unused portion of the UHF spectrum used for TV broadcast.  The FCC has completed a rule making process and systems are now operational. The UK and Canada are in the process of finalizing rules for similar sharing schemes.

With the recent publication of the PCAST report on Spectrum Sharing the scope of geolocation databases has expanded significantly. This workshop will review the latest activities of geolocation databases in TV white space including technology, deployments, regulation and standards efforts. It will then offer a strategy to expand the geolocation database of TV White Space into other spectrum bands, focusing on the reuse of TV white Space technology and the new challenges. The tutorial will wrap up with a discussion on areas for further study and innovation.
