未来数字TV的MIMO-OFDM方案对载波频偏的鲁棒性

Robustness of MIMO-OFDM Schemes for Future Digital TV to Carrier Frequency Offset

Youssef Nasser, Jean-François Hélard, Matthieu Crussière

摘要:

研究了载波频偏对下一代地面数字电视系统中不同高频谱效率MIMO-OFDM方案性能的影响。我们发现,所有研究的MIMO-OFDM方案是敏感的CFO时,它是大于1%的载波间间隔。我们还表明,Alamanti方案是对CFO最敏感的MIMO方案

英文摘要:

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
