Which signal degradation increases when a Discrete Fourier Transform processing block introduces spectral leakage in orthogonal frequency-division multiplexing?

💡 Explanation

Increased inter-channel interference rises because spectral leakage causes energy spreading. The DFT's imperfect windowing allows frequencies outside the intended subcarrier to appear, therefore adjacent channels get corrupted, rather than experiencing power reduction and thus leading to bit errors.
