Spectrum Occupancy Survey In HULL-UK For Cognitive Radio Applications: Measurement & Analysis

摘要

Abstract: - Efficient use of the radio spectrum is a necessity for future wireless systems. Cognitive Radio (CR) systems promise large increases in spectral efficiency. An important design constraint for systems is understanding of the current use of frequency bands which may be used by future CR systems. This paper describes a set of spectrum occupancy measurements performed in Hull, UK, in November 2012 and proposes long-term studies in a single location. Observations provide evidence that the licensed spectrum is far from fully utilized in frequency. Measurements provide evidence of the spectral efficiency benefits that may be accrued by the dynamic reuse of the available spectrum. Such improved usage could break the current spectrum availability bottleneck. The measurement method is based on the energy detection principle.
