← TechnologyWhich outcome occurs when the *pilot symbol insertion* process within a 5G cellular *channel estimator* fails due to a software bug?
A)Reduced spectral efficiency results✓
B)Increased battery energy consumption
C)Elevated inter-cell handoff latency
D)Compromised user equipment authentication
💡 Explanation
Reduced spectral efficiency occurs; pilot symbol insertion supports accurate channel estimation allowing coherent demodulation. Failure decreases channel estimation accuracy because the receiver cannot correctly decode the signal, therefore limiting data throughput rather than affecting issues like battery life or handoff.
