Channel Modeling for Mobile Terminals in Static Indoor Conditions
نویسندگان
چکیده
The number of customers who use cellular phones indoors is rapidly increasing. In this case, the mobile terminals are basically static and the communication characteristics are wildly different from those seen in outdoor moving use. On the other hand, indoor wireless access systems such as WLAN also become widely used. In static usage, the terminal itself doesn’t move, but the environment around it change due to the movement of people, for example. In order to accurately evaluate the communication characteristics, a new propagation model (channel model) is necessary. However, few physical channel models have been for static indoor conditions [1]. In this paper, we propose a physical channel model for static terminals used in the indoor Non Line of Sight (NLOS) and Line of Sight (LOS) conditions. Analysis results of proposed model are compared against measured results and we show that the proposed model can well predict the measured results.

متن کاملDesign of MIMO Antennas for Indoor Base Station and Mobile Terminal
Two design parameters, SNR and correlation, are key factors for enhancing channel capacity in MIMO systems. Achieving high SNR and low correlation is desirable in antenna design. This paper discusses the relation between channel capacity and these two parameters, and presents simple formulas of this relation for propagation channels and antenna coupling of mobile terminals. According to these g...

Linear space-time equalization is shown to be effective in coping with the complicated propagation conditions for wireless broadband communication in an industrial indoor environment. This is demonstrated by realistic simulations that use real channel measurement data obtained from a vector channel sounder for modeling the influence of the radio channel. The system parameters are similar to the...
