On Statistical Distribution of the Largest Eigenvalue of Channel Correlation Matrix in MIMO Multi-Keyhole Environment

Abstract (in Japanese) (See Japanese page) 
(in English) MIMO leads to dramatic improvement in channel capacity and link reliability of wireless systems. However, a MIMO channel has only one degree of freedom in the keyhole environment. As this result, it reduces achievable channel capacity and link quality. This paper proposes the MIMO repeater system that is mitigated to reduce MIMO channel capacity, which can provide a multi-stream transmission in the multi-keyhole environment. Limit of the transmission performance of MIMO is given singular value or eigenvalue essentially, hence we consider a representation by an approximate equation of the probability density function of the largest eigenvalue connecting to the theory of space diversity. It is shown that calculated values based on the proposed method agree well with simulated values.
