Abstract :
This paper investigates the impact of carrier frequency offset (CFO) on the performance of different MIMO-OFDM schemes with high spectral efficiency for next generation of terrestrial digital TV. We show that all studied MIMO-OFDM schemes are sensitive to CFO when it is greater than 1% of inter- carrier spacing. We show also that the Alamouti scheme is the most sensitive MIMO scheme to CFO.
