ICI Mitigation in MIMO OFDM Systems

It is proved that the intercarrier interference matrix in orthogonal frequency division multiplexing systems is unitary for an arbitrary value of frequency offset and any number of subcarriers. The benefit of a recently published precoding scheme in practical applications is thereby established.
