Robustness of MIMO-OFDM Schemes for Future Digital TV to Carrier Frequency Offset (0809.5016v1)

Published 29 Sep 2008 in cs.NI

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
