Analysis of Search Schemes in Cognitive Radio
Ling Luo, Sumit Roy · 2007
Cognitive Radio systems face an important challenge - fast and reliable channel searching to enable secondary users to optimize available spectral resources. We revisit conventional urn models for channel occupancy and analyze the performance of several search schemes in terms of the mean time to detection. In particular, we focus on correlated Markov models for bin occupancy and highlight the performance of n-step serlal search (nSS) algorithm
