← TechnologyWhich outcome occurs when a multi-path signal arrives at a decoder following adaptive equalization processing in a wireless telecommunications system?
A)Amplitude fading increases significantly
B)Symbol synchronization becomes impossible
C)Bit error rate (BER) decreases✓
D)Signal bandwidth remains unchanged
💡 Explanation
Adaptive equalization mitigates the effects of multi-path interference because it uses a feedback loop to adjust filter coefficients and minimize signal distortion. Therefore, the bit error rate decreases rather than increases amplitude fade; the temporal dispersion is reduced.
