Towards Optimized Coexistence of IEEE 802.22 and DTMB: Protection Ratios and Interference Analysis

Abstract

The rapid growth of wireless services has intensified spectrum scarcity, yet paradoxically, studies indicate that spectrum remains underutilized. To address this inefficiency, Dynamic Spectrum Access (DSA) systems have emerged as promising solutions. In particular, the use of TV White Space (TVWS) systems has shown potential for extending connectivity, e.g., via IEEE 802.22 standard-based networks. However, there is limited literature specifically examining the coexistence of IEEE 802.22 networks with Digital Terrestrial Multimedia Broadcast (DTMB) served areas. This paper seeks to address this gap to establish a reference framework for deploying IEEE 802.22 services alongside DTMB broadcasts. The study focuses on determining the necessary protection ratios for optimal performance of both standards and identifying transmission modes that minimize interference between them.
