← TechnologyWhich outcome occurs when adaptive equalization fails in complex QAM?
A)Increased bit error rate✓
B)Channel capacity decreases
C)Reduced power consumption
D)Improved spectral efficiency
💡 Explanation
Increased bit error rate arises because multipath distortion causes intersymbol interference. Adaptive equalization employs digital signal processing to mitigate this, therefore when equalization is insufficient, increased bit errors are inevitable, rather than improved data transmission.
