Binary is Good: A Binary Inference Framework for Primary User Separation in Cognitive Radio Networks
13 years 6 months ago
Primary users (PU) separation concerns with the issues of distinguishing and characterizing primary users in cognitive radio (CR) networks. We argue the need for PU separation in t...
