Statistical Multipath Propagation Modeling for Broadband Wireless Systems

Statistical Multipath Propagation Modeling for Broadband Wireless Systems

This paper surveys and introduces propagation studies and models that are expected to contribute to the development of broadband wireless systems. The survey focused on theory-based propagation models, experimental measurement data useful for modeling, and transmission characteristic evaluations using propagation models. The survey did not attempt to cover all papers in the research fields, but...

Fast Sparse Multipath Channel Estimation with Smooth L0 Algorithm for Broadband Wireless Communication Systems

Broadband wireless channels are often time dispersive and become strongly frequency selective in delay spread domain. Commonly, these channels are composed of a few dominant coefficients and a large part of coefficients are approximately zero or under noise floor. To exploit sparsity of multi-path channels (MPCs), there are various methods have been proposed. They are, namely, greedy algorithms...

Multipath Measurements and Modelling for Fixed Broadband Wireless Systems in a Residential Environment

We describe and analyze measured wideband 29 GHz propagation data collected in Ottawa in 1997, to suggest a simple tapped delay line multipath channel model for residential environments. Purpose To aid in the PHY Task Group's preparation of a detailed evaluation table for performance of PHY layer air interface proposals. Notice This document has been prepared to assist the IEEE 802.16. It is of...
