What is diversity multiplexing tradeoff?

The diversity–multiplexing tradeoff is essentially the tradeoff between the error probability and the data rate of a system. A common way to study this tradeoff is to compute the relia- bility function from the theory of error exponents [10].

What is MIMO diversity?

In wireless and mobile communication, multiple-input and multiple-output (MIMO) is a technique that multiplies the capacity of a communication system when more than one transmit and receive antennas are available to utilize multipath propagation property of EM waves.

What is multiplexing gain?

Spatial multiplexing gain. MIMO channels offer a linear increase in capacity without additional power or bandwidth. This gain is referred as spatial multiplexing gain. The spatial multiplexing gain is realized by transmitting independent data signals from individual antennas.

What is diversity order?

For a system transmitting over frequency selective fading channels, the diversity order can be defined as the number of multi-paths if multi-paths have all equal energy. However, diversity order may not be adequately defined when the energy values are different.
