Abstract:TV White Space (TVWS) is becoming a useful communication medium through cognitive radio techniques. IEEE 802.22 Wireless Regional Area Network (WRAN) has been adopted as a standard in this regard. WRAN has a coverage radius of up to 30km. Due to large cells and opportunistic spectrum utilization, the self-coexistence situation, where multiple WRAN Base Stations (BSs) share the same spectrum band in the same region, is expected to be common. This paper explores the use of relay-based WRANs to improve the transm… Show more
