- Abstract
- In this paper, we study on channel eigenvalue distribution of MIMO system, namely, DAS-to-DAS system, of which transmit and receive nodes are geometrically distributed in unplanned manner. It offers key to performance upper bound analysis of collaborative transmission in unplanned network and multi-user transmission of distributed antenna system. Previous studies on stochastic geometry have analyzed performance of single typical receiver, while transmitters are geometrically distributed. And random matrix theory has unveiled probabilistic behavior of MIMO channel eigenvalues, while transmit and receive antennas are collocated. Our study integrates knowledge from the two different research fields to extend the applicability to analysis on channel eigenvalue distribution of DAS-to-DAS system. As a preliminary research on such channel eigenvalue distribution, its first few moments are derived in analytic form. And its coherency of the analysis results with Monte-Carlo simulation results has examined.
