Threshold setting is a challenging task in spectrum sensing. Adaptive threshold setting outperforms the performance of fixed threshold setting. This paper presents the results of both static and mobile spectrum occupancy measurements carried out in the Pathum Thani province, Bangkok, and the Mae Kasa sub-district of Thailand using a low-cost spectrum analyzer based system using fixed threshold setting technique to show the spectrum occupancy at UHF TV band for testing the feasibility of TV White Space (TVWS) technology. Furthermore, inaccuracy of fixed threshold setting while performing spectrum occupancy measurements is shown by comparing the data with the ground truth report from the National Broadcasting and Telecommunications Commission (NBTC). An adaptive threshold setting algorithm, namely, Forward Consecutive Mean Excision (FCME) are then applied for determining the performance while carrying out spectrum occupancy measurements. Additionally, the adaptive threshold setting is modified to improve the detection performances making the resultant spectrum occupancy more reliable. The proposed technique of adding noise in the FCME algorithm is then optimized to determine the appropriate percentage of noise to be added to make the FCME algorithm more reliable. Furthermore, localization algorithm based on double-thresholding (LAD) and the enhanced version of LAD, i.e., LAD with adjacent cluster combining (ACC) is applied for reliable signal detection. |
