Which limitation arises in Orthogonal Frequency Division Multiplexing (OFDM) due to imperfect synchronization between transmitter and receiver during signal reconstruction?

💡 Explanation

Imperfect synchronization leads to inter-carrier interference (ICI) because the orthogonality between sub-carriers is disrupted, hence signals from adjacent subcarriers bleed into the desired carrier. Therefore, carrier isolation degrades rather than improving, under these conditions.
