A Markov Model for Indoor Ultra-wideband Channel with People Shadowing
نویسندگان
چکیده
For an indoor ultra-wideband (UWB) communication system, the line-of-sight (LOS) between the transmitter and receiver may be frequently blocked by moving people. Blocking of LOS may significantly affect the quality of service of on-going UWB communications. Based on the Angular Power Spectrum Density and the human blocking models, we build a packet-level UWB channel model considering the shadowing processes based on a Finite-state Markov Chain. The model is simple enough to be incorporated into existing network simulators like NS-2 and it can be used to facilitate protocol design and quality of service analysis for UWB based wireless personal area networks.

In this paper an experimental characterization of a typical indoor wireless propagation channel is performed. This channel characterization is needed for short range applications (<10m), utilizing Ultra-Wideband Impulse Radio (UWB-IR) techniques. Both the line of sight (LOS) and the non line of sight (NLOS) scenarios are taken into account. The characterization is done using time domain measure...
متن کاملOutage Probability Bound and Diversity Gain for Ultra-Wideband Multiple-Access Relay Channels with Correlated Noises
In this paper, Ultra-wideband (UWB) multiple access relay channel with correlated noises at the relay and receiver is investigated. We obtain outer and inner bounds for the IEEE 802.15.3a UWB multiple access relay channel, and also, a diversity gain bound. Finally, we evaluate some results numerically and show that noise correlation coefficients play important role in determining relay position.
متن کاملUWB Channel Modeling Based on Wideband Indoor Channel Measurements at 2.4, 4.75, and 11.5 GHz
Using the wideband indoor channel measurements data at 2.4, 4.75 and 11.5 GHz of [1], a statistical Ultra Wide Band (UWB) channel model is determined. Employing different windows (i.e. Rectangular, Hanning and Blackman-Harris), the impulse response model for the UWB channel is obtained and accordingly, major channel parameters such as path loss exponent, shadowing, root mean square (rms) delay ...
متن کاملUltra Wideband Channel Model for IEEE 802.15.4a and Performance Comparison of DBPSK/OQPSK Systems
Ultra Wideband (UWB) is a radio technology that can be used at very low energy levels for short-range high-bandwidth communications by using a large portion of the radio spectrum. Ultra Wideband (UWB) systems transmit signals across a much wider frequency than conventional systems and are usually very difficult to detect. The focus of this research is to model the Ultra wideband (UWB) channel f...
