A Comparative Performance Analysis of Interweave and Underlay Multi-Antenna Cognitive Radio Networks

In this paper, an analytical performance study for multi-antenna Cognitive Radio (CR) systems is presented. The two most popular CR approaches, namely, the interweave and underlay system designs, are considered and based on the derived analytical framework, a throughput-based comparison of these two...
