| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We propose a sparse signal reconstruction algorithm from interlaced samples with unknown offsets based on the $l_1$-norm minimization principle. First, it minimizes the $l_1$-norm with the offset parameters fixed. Second, the minimum value is further minimized with respect to the parameters. Even though this is a heuristic approach, the computer simulations show that the proposed algorithm perfectly reconstructs sparse signals under certain conditions. The proposed approach is attractive because of its computational efficiency compared to a combinatorial optimization approach, which is almost impossible even for a small size of problems. | |
