Spectrum sensing based on energy detection. Due to multipath and shadowing effects in practical channels, the performance of individual cognitive user spectrum sensing is degraded. Therefore, cooperative spectrum sensing among different users is required to mitigate these effects. This design requires implementing a collaboration mechanism where two users perform cooperative spectrum sensing to improve primary user detection rates, reduce detection time, and achieve agility gain. Simulation results must be provided, including energy calculation algorithms and decision fusion techniques.
