It is the pursuit of a multiple-input-multiple-output (MIMO) system to approach and even break limit channel capacity. However, it always big challenge efficiently characterize MIMO systems in complex space get better propagation performance than conventional considering only free space, which important for guiding power phase allocation antenna units. In this manuscript, an Electromagnetic-Information-Theory (EMIT) based model developed efficient characterization space. The...
Pushing the information states' acquisition efficiency has been a long-held goal to reach measurement precision limit inside scattering spaces. Recent studies have indicated that maximal states can be attained through engineered modes; however, partial intrusion is generally required. While non-invasive designs substantially explored across diverse physical scenarios, of dynamic spaces remains challenging due intractable non-unique mapping problem, particularly in context multi-target...
The influence of coupling effect on the channel capacity multiple-input multiple-output (MIMO) system is introduced through effective rank, which numbers MIMO. Different from MIMO composed isotropic point sources/receivers, this paper considers a half-wavelength antenna array as sources. Then ranks with are compared noncoupling results based method moments (MoM). show may not always lead to decrease capacity. By incorporating mutual properly, will be increased.
The electromagnetic channel effective rank of multiple-input multiple-output (MIMO) system describes its number, which directly characterizes the performance and is widely used in communication systems. In this work, positions MIMO transmitting array elements are optimized to achieve maximum rank. Specifically, a linear with fixed aperture size considered as antennas system, isotropic point receivers model receivers. matrix mutual coupling effect can be derived from method moments (MoM)....
On-demand wave field control is the key goal of research, but optimal states in disordered environments are always a difficult problem. The electromagnetic information theory (EMIT) naturally suitable to solve this problem because it takes into account. Here, we classify known and unknown categories. For environments, use group T-matrix method mode decomposition get states. environment, non-iterative operator characterize properties scatters, called D based on EMIT. To further demonstrate...
<title>Abstract</title> Pushing the information states acquisition efficiency has been a long-held goal to reach measurement precision limit inside scattering spaces. Recent studies point out that maximum can be achieved by engineered modes with specific matrices and operators, however, they typically necessitate time-consuming iterations or partial intrusion for multi-targets. Whereas non-invasive designs have substantially explored across various physical scenarios, acquiring...
Effective degrees of freedom (EDOF) a multiple-input-multiple-output (MIMO) system is the number equivalent independent single-input-single-output (SISO) channels, which represents channal performance. In this paper, three-band MIMO operating at millimeter waves designed, and method characteristic mode analysis (CMA) combined with EDOF proposed. Based on electromagnetic information theory, channel matrix corresponding different modes for antenna array are calculated. Finally, by comparing...
Modern antenna systems face serious problems of mutual coupling, which will cause electromagnetic compatibility such as pattern distortion. This article presents an innovative methodology for adaptive coupling compensation based on the efficient characterization coupled arrays (CAAs), especially nonuniform configurations. As a data-driven methodology, CAAs is conducted firstly to simplify analysis by utilizing characteristic modes individual elements, resulting in more data-collection...
