Module: Antenna Diversity

We study how to achieve antenna diversity with multiple antennas.

Dates: Wed, Feb 21 - Wed, Feb 28

Learning Outcomes

Time diversity

You understand what is antenna/spatial diversity.
You understand space-time codes, and in particular, the Alamouti scheme.
You understand the concept of degrees of freedom.
You understand the tradeoff between diversity gain and spatial multiplexing in MIMO systems.

Readings

Overview

Receive diversity

Receive diversity is similar to time diversity

Transmit Diversity

Need to be clever to achieve transmit diversity

Space-time codes

Utilize spatial and temporal dimensions
