Abstract

Smart antenna systems are becoming practical for indoor applications such as wireless local area networks. However, the challenging indoor propagation environment is one of biggest obstacles for designing smart antenna wireless networks. In order to fully understand and characterize channel propagation characteristics or vector channels of smart antenna systems in indoor environments, experiments are conducted using a 1.8 GHz real-time smart antenna testbed with a uniform linear array. The effects of mobile user motion on the vector channel variation are studied in line-of-sight (LOS) and non-line-of-sight (NOLOS) indoor scenarios. The experimental results on the variation of vector channel parameters such as space-time correlation properties, spatial signatures, direction-of-arrivals, multipath angle spread, and complex path fading are presented. Results show that the vector channel varies more significantly in the NOLOS scenario than in the LOS scenario.
