Propagation Model and Performance Analysis for Mobility Constrained Indoor Wireless Environments

Author:
Description:
In an indoor wireless environment like an open office or laboratory, there are not enough large obstacles to reflect or refract the main waves contributed by the scattering clusters visited by the mobile user. Moreover, mobile WLAN users generally restrict their movements to a small area due to the inability of most WLAN standards to accommodate hand-offs. As a result, users visit at most one or two scattering clusters and experience only a handful of different shadowing values. This thesis proposes the first ever appropriate composite fading / shadowing channel model that characterizes the combination of small scale fading and large scale shadowing for users confined to small coverage areas in a large office environment described above. Based on a detailed indoor measurement campaign, a joint distribution called the Joint fading and Two-path Shadowing (JFTS) distribution is proposed that combines the Rician fading and the two waves with diffuse power (TWDP) shadowing models. This thesis also presents the first ever analysis of different performance metrics like outage probability, error rate performances and spectral efficiencies of existing high throughput communication techniques like error control coding, fixed and adaptive modulation in mobility constrained indoor wireless environment, where the propagation scenario can be appropriately characterized by the newly developed JFTS model. Performance evaluation is done both in presence or absence of perfect channel state information.
