Abstract

The invention discloses a virtual source theory-based a modeling approach for a six-polarized MIMO (multi-input multi-output) channel. The modeling approach comprises the following steps: calculating the six-polarized channel matrix Hlos in a free space channel, determining the position of each virtual source, determining the contribution of each virtual source to the receiving of each component of an electromagnetic field according to a boundary condition, calculating the channel matrix Hi (i=1, ..., N) corresponding to each virtual source, and adding the contribution of a direct signal in a free space to the contribution of each virtual source to obtain the total channel matrixes. The modeling approach can be applied to design and performance estimation of a multi-polarized MIMO system in wireless communication.

Description

technical field [0001] The invention relates to the field of MIMO wireless communication, in particular to a 6-polarization MIMO channel modeling method based on virtual source theory. Background technique [0002] With the rapid development of various high-data-rate wireless services such as mobile multimedia and mobile Internet, the demand for bandwidth in wireless communication networks continues to increase. However, the wireless spectrum is a non-renewable resource, so the limited bandwidth will seriously restrict the development of future high-speed wireless communication systems. Researchers of wireless communication have to re-examine the information transmission capability of electromagnetic waves in order to obtain a wireless transmission technology with higher spectral efficiency. Due to its great potential in spectrum utilization and network coverage, MIMO technology has become an indispensable core technology in a variety of new-generation wireless information ...
