Ten Years of Cognitive Radio: State of the Art and Perspectives

Edited by: Friedrich Jondral, Zander (Zhongding) Lei,Joseph Mitola and Jacques Palicot

  1. Content type: Review

    Cognitive radio has been proposed as a solution for the problem of underutilization of the radio spectrum. Indeed, measurements have shown that large portions of frequency bands are not efficiently assigned si...
