Range estimation using phase difference of arrival technique

The principle of positioning is a technology of identification that enables object, people and/or assets to be tracked. This is basically to allow objects to be found for the purpose of rendering/obtaining services. Ranging technique therefore is an important part in anchor nodes location vis-à-vis...
