Which outcome results at a base station when high interference disrupts orthogonal frequency-division multiplexing?

A)Increased bit error rate
B)Higher carrier signal power
C)Decreased subcarrier spacing
D)Improved signal-to-noise ratio

💡 Explanation

Increased bit error rate occurs because inter-carrier interference, corrupts orthogonality, disrupting the discrete Fourier transform at the receiver; therefore decoding errors increase, rather than exhibiting better SNR due to interference mitigation techniques.
