An Electromagnetic Information Methodology for Fast MIMO Deterministic Channel Analysis

The electromagnetic information theory (EIT) is a general methodology framework, which should be able to achieve the wireless network design and performance analysis. Its one of the main objective is exploring how to increase spectral efficiency of the multiple input multiple output (MIMO) communication. The array arrangements, mutual-coupling effects between antennas, and antenna radiation characteristics may play important roles. Therefore, the electromagnetic (EM) theory will be a non-negligible analysis tool in the EIT. In this paper, we present an electromagnetic information methodology (EIM) combining the EM theory with information theory for the fast and accurate MIMO channel analysis. This methodology decouples MIMO antenna arrays with propagation environments, of which advantages are as follows: 1) for channel analysis of variable MIMO array arrangements, it avoids inefficient recalculation of complex and large-scale propagation environments; 2) It can determine the antenna radiation characteristics that achieves capacity maximization for the given propagation scenario; 3) The EM computation techniques can be applied in this framework, which makes the methodology more practical.
