| Outline of Final Research Achievements |
We have developed reconstruction methods of a (possibly sparse) discrete-valued vector from its underdetermined linear measurements, and applied the methods to various problems in communications. Main results are as follows. 1) development of low computational complexity reconstruction algorithms of a discrete-valued vector. 2) theoretical analysis on the condition for the perfect reconstruction via the proposed methods. 3) demonstrations of the effectiveness of the proposed approach through applications to various problems in communications.
