← TechnologyWhich consequence results when adaptive channel estimation fails in a mobile communication system?
A)Reduced battery drain occurs
B)Elevated signal-to-noise ratio occurs
C)Increased inter-symbol interference rises✓
D)Lower base station power consumption
💡 Explanation
Increased inter-symbol interference increases because when channel characteristics change rapidly requiring adaptive channel estimation to compensate to demodulate signals correctly. Therefore, ISI rises rather than lower battery drain which would be a separate power management issue.
