Which outcome occurs when a Fast Fourier Transform fails to adequately resolve closely spaced frequency components in Orthogonal Frequency Division Multiplexing?

💡 Explanation

Increased inter-carrier interference emerges in OFDM because inadequate frequency resolution during the Fast Fourier Transform leads to signal bleed between subcarriers. Therefore, interference occurs, rather than improved error rates, because subcarrier orthogonality degrades under these filter conditions.
