| Outline of Final Research Achievements |
We have studied basic theory which provide a basis of the technology for signal sensing and estimaion from a large scale radar sysytem or a rerilable and secure communication via multi input and output channels(MIMO) using large scale multi-anntenas. Specifically, we considered a theoretical model of the information sensing from a large-scale radar and elucidated the theoretical limit of the signal estimation and the optimal communication shceme attaining this limit, providing an index for the communication engineers to design communication systems. In the security analysis of the communication using the large-scale antenna, we introcuce a new realistic problem setting that we have a resoruce constraint on use of random numbers to enhance a security of the message. Under this new problem formitaionds. We clarified a theoritical limit of the secure communication.
