| Abstract(in English) | For efficient spectrum sharing between heterogeneous wireless systems, statistical information regarding spectrum use by incumbent systems is useful. In this work, we suppose to estimate statistical information based on FFT-ED (Energy Detection based on FFT)-based spectrum measurement. In FFT-ED, noise floor has to be estimated to set a detection threshold appropriately. In general, noise floor has a frequency dependency and its level varies in time. Therefore, we investigate a noise floor estimation considering the shape and level of the noise floor. Specifically, we propose a method which can estimate the noise floor level while performing spectrum measurement exploiting a prior information regarding the shape of noise floor and an outlier detection algorithm (FCME: Forward Mean Consecutive Mean Excision). We justify the proposed method by means of computer simulation and actual measurement. |
