Which consequence results when phase distortion modifies OFDM subcarrier functions?

A)Increased bit error rate
B)Reduced spectral power density
C)Enhanced signal-to-noise ratio
D)Decreased intersymbol interference

💡 Explanation

Increased bit error rate occurs because phase distortion degrades the orthogonality of the subcarriers via intercarrier interference, impacting demodulation accuracy; therefore the BER increases, rather than improving the noise robustness.
