Abstract

In this letter, a dual-hop detect-and-forward cognitive relaying system with interference constraints over general α-μ fading channel is studied. The contribution is first described by the exact closed-form expression for the outage probability and later extended to the symbol error rate calculation. Both analytical and simulation results show how the outage saturation paradigm appears when the interference level is constrained. Also, it is shown that the system achieves a better performance when higher interference constraint is employed.
