    • Low complexity 2-level (FFT-GOERTZEL) spectrum sensing method for cognitive radio 

      Bhatt, Prakruti Vinodchandra (Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
      Energy detection in frequency domain is a preferred technique for the spectrum sensing and the accuracy of frequency estimation depends on the Discrete Fourier Transform (DFT) size. Instead of computing full length (N) ...

    • Multiband cooperative spectrum sensing in cognitive radio networks 

      Pathak, Anusha (Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
      Spectrum Sensing forms one of the most important functions of Cognitive Radio operation. Energy detection is a less complex spectrum sensing technique which does not need knowledge of Primary User (PU) signal. An Energy ...

    • Spectrum sensing in cognitive radio networks 

      Ahir, Sagar J. (Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
      In this thesis, we consider the problem of secondary users’ selection for cooperative spectrum sensing in cognitive radio networks. We assume that the secondary users involved in sensing transmit their spectral energy ...
