Abstract (in Japanese) (See Japanese page) 
(in English) Frequency domain channel estimation approaches are widely used for the channel estimation of uplink OFDMA (Orthogonal Frequency Division Multiple Access) systems, since the number of available pilots is limited.
To improve the estimation performance, a time domain compressed sensing based channel estimation method has been proposed.
The method also has an advantage that channel responses of whole subcarriers can be obtained, while the estimation accuracy of non-allocated subcarriers degrades for the case with localized subcarrier allocation.
In this paper, we propose a time domain compressed sensing based channel estimation method using cyclic delay pilot signal, which enables us to share pilot subcarriers with all users and thus to improve the estimation accuracy regardless of subcarrier allocation strategies.
The performance of the proposed method is demonstrated via computer simulations.
