On the performance of spectrum sharing systems over α-µ fading channel for non-identical µ parameter
Spectrum sharing is a promising approach in cognitive radio networks to improve the spectrum utilization of wireless communication systems. In this paper, we analyze the performance of spectrum sharing systems under the peak interference power constraint for a general fading model, namely the α-μ fading channel. In particular, we derive expressions for statistical characteristics such as probability density function and cumulative distribution function of the end-to-end signal-to-noise ratio for dissimilar fading parameter μ. Using these statistics, we obtain the closed-form expressions for outage probability, amount of fading and approximate ergodic capacity for the considered spectrum sharing system. Finally, Monte Carlo simulations are presented to verify the analytical results.
