MIMO OFDM is a promising technique for the future wireless communications. However, the performance of MIMO OFDM systems is very sensitive to carrier frequency offset (CFO) which introduces inter-carrier-interference (ICI). Therefore, frequency synchronization is a critical problem in MIMO OFDM systems. In this paper, we study the problem of frequency synchronization in MIMO OFDM systems and propose...
The combination of Multi-Input Multi-Output (MIMO) with Orthogonal Frequency Division Multiplexing (OFDM) is regarded as a promising technique for the future wireless communications. However, the performance of MIMO OFDM systems is very sensitive to carrier frequency offset (CFO) which introduces inter-carrier-interference (ICI). Consequently, CFO estimation plays a key role in MIMO OFDM systems....
