Frequency Offset Estimation and its Compensation in an Uplink Virtual MIMO System Using OFDM

Abstract (in Japanese) (See Japanese page) 
(in English) We need a wider frequency bandwidth for high-speed transmission,
and thus a higher frequency band will be used in future mobile communications. However, the propagation loss increases in a higher frequency band. It causes degradation of communication quality especially for an uplink channel because the power is supplied by the terminal battery. Then, it has been proposed that a communication terminal cooperates with nearby terminals to solve this problem. However, different frequency offsets of the terminals cause different phase rotations. In this paper, we propose a frequency offset estimation and compensation scheme of them. We evaluate the performance of the virtual MIMO-based OFDM communications using the compensation scheme.
