    Incumbent user active area detection for Licensed Shared Access

    Full text link
    © 2015 IEEE. Licensed Shared Access is a European standardisation effort which promotes repository based quasi-static hierarchical spectrum sharing. In this scheme the sharing time base is in the order of months if not years. For widespread use of Licensed Shared Access, shrinking the sharing time base is crucial. In this paper we propose a scheme to reduce the sharing time base to seconds or minutes scale. We present a new technique named lightweight Radio Environment Map based on a Kalman Filter derived from geo-location aware spectrum measurements, which can be run at the shared access licensee end. Our objective is to determine the active area of a static or slowly moving incumbent. We consider a challenging scenario where a large fraction of measurements is missing and the available measurements are highly distorted. Performance of our incumbent active area detection approach is evaluated by simulating a low power incumbent in an urban cellular environment. Simulation results show a substantial improvement of missed detection area in comparison to the counterpart that does not use our lightweight Radio Environment Map

    A Road Taken: A Cataloging Team Becomes a Metadata Team

    This chapter describes the issues confronted along the “road taken” by a technical services team as it transitioned from traditional monographic cataloging to metadata for digital collections. To serve changing user needs, the team shifted focus to providing quality metadata. Along this road, the team confronted and welcomed a number of changes. These included a unit merger, off-site relocation, shedding the cataloging role, learning how to produce metadata, identifying areas for growth with a library-wide Metadata Summit, working with new stakeholders, and managing new staff and faculty. The chapter concludes with the lessons the team learned and its prospects
