The multicarrier faster-than-Nyquist (MFTN) system is attractive to ultra-high definition TV because it improves on the spectral efficiency up to twice that of the conventional orthogonal frequency division multiplexing system. However, the MFTN system causes the inter channel interference (ICI) by corrupting the orthogonality between subcarriers. In this paper, a pilot pattern for the MFTN system is proposed to improve synchronization performance by removing the ICI in pilot subcarriers while preserving the advantage of the MFTN scheme. To remove the interference, the known pilot pattern is intentionally distorted according to the amount of the interference at the transmitter to improve on the performance of synchronization without affecting the net data.
