Abstract

The word Diversity in the dictionary implies variety in form. And the basic concept derived from these principles is that if one has multiple copies of the same system, presumably one would have a better chance of achieving the desired goals. The fundamental problem with this simplistic way of reasoning is that one needs to understand the physical environment where such an experiment needs to be carried out and how one should interpret the final result. The current state of the art applies some statistical framework to the physical scene to explain the added advantage of diversity. To appreciate the true physical significance of diversity we have to go back to the roots! We need to understand first what the statistical framework implies and secondly how it relates to the problem at hand. So we need to address the following questions: 1. Who first introduced the concept of ensemble averaging in physics and in what context? 2. What is the physical significance of ensemble averaging? 3. How does ensemble averaging apply to the vector antenna problem?
