Abstract (in Japanese) (See Japanese page) 
(in English) Recently, the superimposed pilot channel estimation has attracted attention for wireless communications,
where the pilot symbol sequence is superimposed on a data symbol sequence and transmitted together, and thus there is no drop in information rate.
In the superimposed pilot channel estimation,
the receiver correlates the received symbol sequence with the pilot symbol sequence, and obtains the channel estimate.
However, the correlation between the pilot symbol sequence and the data symbol sequence deteriorates the channel estimation accuracy.
On the other hand, it has been well known that the SAGE algorithm is an effective method for channel estimation and data detection.
This algorithm is particularly effective in MIMO systems, because the operation of this algorithm can cancel the interference from other transmit antennas.
In this report, we propose a SAGE algorithm for channel estimation and data detection using superimposed pilot channel estimation in MIMO systems.
