Relay-Based Cooperative Spectrum Sensing

In this chapter, the detection accuracy of an AF relay-based CSS approach over non-identical Nakagami-m fading channel is investigated. New exact and approximated closed-form expressions are derived for the average detection probability and the average false alarm probability over two diversity combining techniques: MRC scheme and SC scheme. The convergence rate of infinite series that appears in the derived exact closed-form expressions are also investigated and proposed a powerful acceleration algorithm that allows for the series termination with a finite number of terms.
