Diversity Combining TechniquesDiversity Combining Techniques When the required signal is a combination of several plane waves (i.e, multipath), the total signal amplitude may experience deep fades (i.e, Rayleigh fading), over time or space. The major problem is to combat these deep fades, which result in system outage. Most popular and efficient technique for doing so is to use some form of diversity combining Diversity: multiple copies of the required signal are available, which experience independent fading (or close to that) Types of diversity. 3/11/2003 Lecture 17: ELG7178W: Smart Antennas S. Loyka, Winter 2003 1 Types of Diversity Space diversity. Antennas are separated in space Angle diversity. Multiple copies of the required signal have different AOA’s Frequency diversity. Multiple copies are transmi……
