A Novel Radio Mode Identification Approach for Spectrum Sensing in Cognitive Radios
نویسندگان
چکیده
The paper suggests a radio mode identification algorithm for spectrum sensing that utilizes time frequency analysis and digital image processing techniques to identify various transmission parameters of the primary users. Identification of the spectral holes within the frequency band under observation has been of major interest in the research on spectrum sensing techniques; however the proposed approach enables the cognitive radio to identify spectral behavior of the primary users in addition to identifying the spectrum holes with greater accuracy. The identified parameters can be utilized to decide the suitability of the detected spectrum holes and predict pattern of spectrum usage in near future.
