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.
