| Outline of Final Research Achievements |
We originally planned to study statistical multichannel signal processing for electroencephalogram, but we changed the research plan and focused on the fundamental analysis method, and studied estimation problem with complex multivariate probabilistic distribution. We proposed a statistical approach to estimate correlation coefficient between two complex signal channels under the condition where the phases are unobservable. As a byproduct of this research, we found a maximum likelihood parameter estimation algorithm for bivariate Nakagami-m distribution and Kibble's bivariate gamma distribution. We also proposed maximum likelihood estimation algorithm for Wishart distribution, which is a conjugate prior of multivariate distributions.
