Abstract

It is common sense that coexistence is a key issue for the performance of any wireless technology which intends to operate in unlicensed band. WRAN(Wireless Regional Area Network) is a novel air interface (i. e., MAC and PHY) standards based on Cognitive Radios(CRs) defined by IEEE 802.22 Work Group(WG). It aims to reuse the fallow-TV spectrum without causing any harmful interference to incumbents (i.e., the TV receivers). This paper focuses on the WRAN self-coexistence performance analysis. Through researching the synchronization mechanism in MAC layer, we validate the synchronization convergence rule via modeling and simulation. The simulation results show that a lot of cells can convergence quickly in a square area even they work distributed completely.
