| Summary: | 碩士 === 國立中央大學 === 通訊工程學系 === 102 === In modern wireless communications, Orthogonal Frequency-Division Multiplexing is widely used in a variety of systems such as digital video broadcasting. It turns out that the problem of how to improve the spectrum efficiency is mentioned for real applications. To solve this problem, the cognitive radio schemes are rapidly increasing in the literature. There are three main categories in cognitive radio: spectrum sensing, power control, and spectrum management. This paper studies the spectrum sensing method for DVB-T2 based on pilots to be used with a short cyclic prefix length. The DVB-T2 spectrum is sensed through the specific pilot patterns that are designed in DVB-T2.
