Frequency-Domain Modeling of OFDM Transmission with Insufficient Cyclic Prefix using Toeplitz Matrices
OFDM interference from an insufficient cyclic prefix is modeled with a closed-form Toeplitz DFT formula, revealing that interference is banded near the diagonal and enabling reduced-complexity frequency-domain simulation.
