Enhanced robust cooperative spectrum sensing in cognitive radio

  title={Enhanced robust cooperative spectrum sensing in cognitive radio},
  author={Feng Zhu and Seung-Woo Seo},
  journal={Journal of Communications and Networks},
As wireless spectrum resources become more scarce while some portions of frequency bands suffer from low utilization, the design of cognitive radio (CR) has recently been urged, which allows opportunistic usage of licensed bands for secondary users without interference with primary users. Spectrum sensing is fundamental for a secondary user to find a specific available spectrum hole. Cooperative spectrum sensing is more accurate and more widely used since it obtains helpful reports from nodes… CONTINUE READING

Key Quantitative Results

  • Simulation results show that when holding comparable error rates, the numbers of EWSPRT and EWSZOT are 40% and 75% lower than WSPRT, respectively.
