Abstract :
In the multi-tiered spectrum sharing systems, the exact closed-form expression of the outage probability is derived. It is assumed that the secondary users have different priority to access spectrum. A weighing factor is introduced to identify the intra-tier and inter-tier interference effects. It is observed that the analytical results are well matched with the simulated results.
