Chapter 4. Antenna Diversity
IN THIS CHAPTER
In this chapter, we explore the most underutilized resource in current wireless LAN systems, antenna diversity. Recent information theoretic results suggest that there is tremendous capacity potential for wireless communication systems using antenna diversity. Diversity is defined as multiple independent channels between transmitters and receivers; hence, antenna diversity or polarization discrimination occurs when the independent paths are spatial in nature. That is, there is sufficient spacing between the antenna elements at the transmitters and receivers such that there is no or very little correlation amongst their respective signals. The ...
