Abstract

This paper proposes and compares two new physical layer architectures for cognitive radio. The idea of cognitive radio has been proposed for a while, but little research has been done on detailed architectural design and complexity analysis of physical layer functions and systems. Two cognitive radio functional architectures are proposed: one is based on the traditional communication components and the other is based on blind signal separation. Complexities of critical cognitive radio functions are evaluated and the two proposed architectures are compared.
