On the Performance of Kronecker MIMO Channel Models: A Semi-definite Relaxation Approach
The Kronecker model is a popular structure in the design and analysis of multiple-input multiple-output (MIMO) systems. Despite being criticized for unrealistic results in some cases, it mathematically facilitates the analysis of MIMO transmission schemes. In our earlier work 1, we proposed algorithms in order to determine a MIMO channel covariance matrix which is as far as possible from the Kronecker model based on semidefinite relaxation approach. In this paper, we develop this approach for different case studies. In particular, we verify our proposed algorithms for different size of antennas. Further, as a case study for the relevance of the Kronecker assumption, numerical analysis will be carried out to evaluate the performance of optimal pilot design for Kronecker and non-Kronecker MIMO channels.
