Frequency Reuse over a Single TV White Space Channel

Abstract

By following the discussions on homogeneous coexistence in the previous chapter, we continue investigating this issue in this chapter, but in a slightly-different network environment where the available spectrum is insufficient to satisfy the QoS requirements of multiple CR networks and they may have to share a single TVWS channel. When multiple co-located CR networks operate in the same swath of white-space (or unlicensed) spectrum with little or no direct coordination, co-channel self-coexistence is a challenging problem.
