Abstract

The invention discloses a modeling method specific to an indoor 3D (Three-Dimensional) spatial statistical channel. The modeling method can be applied to a distributed multiple input and multiple output (MIMO) system. When a base station (BS) is designed with a directional antenna, important space-time channel parameters such as Doppler Power Spectrum (DS), space-time correlation and channel capacity are concluded by taking a Poda signal at an MS (Mobile Station) end as a basis; space-time model parameters and the mechanism relationship among included angles of directional antenna main lobes are resolved by using channel space-time feature parameters; meanwhile, the system transmission performance of an MIMO multi-antenna linear array and a circular array under a 3D spatial statistical channel model is researched, so that accurate, flexible diverse channel models are provided for an MIMO multi-antenna space-time processing algorithm and a simulation wireless communication system, and the research of the spatial statistical channel model is expanded.
