A new pilot-aided technique of carrier frequency offset (CFO) and channel estimation is presented for multiple-input multiple-output (MIMO)-orthogonal frequency divisions multiplexing (OFDM) systems.

• 5．将前述基于相关编码OFDM 系统的频偏估计方法推广到多输入多输出（Multiple-Input Multiple-Output，MIMO）-OFDM 系统，同时进一步提出了整数CFO 估计和信道估计技术，得到了一种新的基于数据辅助的MIMO-OFDM 系统载波 频偏和信道估计算法。
