Abstract

Cognitive radio has recently been proposed as an efficient paradigm to solve the spectrum scarcity in modern communication systems. In this paper, we consider spectrum sharing cognitive radio networks that utilize spectrum bands licensed to primary network. Spectrum sharing cognitive radio networks operate by ensuring that interference power at primary receiver remains below a certain threshold. We analyze the performance of the spectrum sharing cognitive radio networks with multiuser selection. Analytical and simulation results show that multiuser diversity gain in each network is substantially larger than that in the conventional wireless networks.
