Performance Analysis of Secondary Link with Cross-Layer Design and Cooperative Relay in Cognitive Radio Networks

In this thesis, we investigate two different system infrastructures in underlay cognitive
radio network, in which two popular techniques, cross-layer design and cooperative
communication, are considered, respectively. In particular, we introduce the Aggressive
Adaptive Modulation and Coding (A-AMC) into the cross-layer design and
achieve the optimal boundary points in closed form to choose the AMC and A-AMC
transmission modes by taking into account the Channel State Information (CSI) from
the secondary transmitter to both the primary receiver and the secondary receiver.
What’s more, for the cooperative communication design, we consider three different
relay selection schemes: Partial Relay Selection, Opportunistic Relay Selection and
Threshold Relay Selection. The Probability Density Functions (PDFs) of the Signal-to-
Noise Ratio (SNR) in each hop for different selection schemes are provided, and
then the exact closed-form expressions for the end-to-end packet loss rate in the secondary
link considering the cooperation of the Decode-and-Forward (DF) relay for
different relay selection schemes are derived.
