← Language & CommunicationIn cognitive radio networks, which outcome occurs when spectrum sensing consistently identifies unused licensed spectrum, but secondary users still experience high interference?
A)Increased sensing algorithm computational complexity
B)Hidden terminal problem exacerbates interference✓
C)Higher signal processing latency overall
D)Channel estimation inaccuracies are magnified
💡 Explanation
The hidden terminal problem causes increased interference even when spectrum sensing indicates available spectrum because some secondary users might not detect each other. The carrier sense multiple access with collision avoidance (CSMA/CA) mechanism fails; therefore, interference rises rather than computational complexity or latency increases.
