Measurement, modeling and simulation of LOS microwave channels
Abstract
A brief summary of prior work in the field of microwave line-of-sight (LOS) channel propagation measurements, channel models, and channel simulators is presented. The objective of these efforts is the reliable prediction of microwave radio performance on any specified link. The ideal channel simulator is one that operates at RF, operates under computer control, is dynamic, stimulates both minimum and nonminimum phase distortions, and has a dual channel capability for the comparative evaluation of space and frequency diversity radios. Significant parameters of this ideal simulator should be based on a model that was validated through propagation measurements on different representative paths. Although much progress was made, a number of issues remain. The work in the area of channel simulation, propagation measurements, and modeling is described. Together with channel measurement programs currently underway, this work should be helpful in the resolution of many of the remaining issues.
