Analytical Evaluation of Adaptive-Modulation-Based Opportunistic Cognitive Radio in Nakagami-m Fading Channels
نویسندگان
چکیده
The performance of adaptive modulation for cognitive radio with opportunistic access is analyzed by considering the effects of spectrum sensing, primary user traffic and time delay for Nakagami-m fading channels. Both the adaptive continuous rate scheme and the adaptive discrete rate scheme are considered. Numerical examples are presented to quantify the effects of spectrum sensing, primary user traffic and time delay for different system parameters.
