## What is multiplexing gain in MIMO?

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.

### How is diversity gain calculated?

In order to find the diversity gain, the power samples of the two branches are combined by selection combining (SC) and maximal ratio combining (MRC) [12]. With SC the branch with the highest power for each of the 3750 equal measurement situations is always selected.

In wireless microphone applications, diversity receivers are often used to improve reception of RF signals. A diversity receiver utilizes two separate, independent antenna systems. The receiver looks at the signal coming in from the each antenna, and determines which one is the stronger.

What is MIMO diversity?

Diversity Coding is the spatial coding techniques for a MIMO system in wireless channels. Fundamentally, diversity coding sends multiple copies through multiple transmit antennas, so as to improve the reliability of the data reception. If one of them fails to receive, the others are used for data decoding.

What is meant by diversity gain?

Diversity gain is the increase in signal-to-interference ratio due to some diversity scheme, or how much the transmission power can be reduced when a diversity scheme is introduced, without a performance loss. Diversity gain is usually expressed in decibels, and sometimes as a power ratio.

## 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. In order to obtain a rough value of diversity order, one may use the number of multi-paths or the reciprocal value of the multi-path energy variance.

### What is the purpose of diversity receiver?

#### What is a diversity receiver?

What is diversity receiver and explain?

A diversity receiver has two antennas for receiving the one signal. If the signal from one antenna has interference, the receiver then uses the signal from the other antenna. A distinction is made between antenna diversity and true diversity. Receivers with no diversity are called non-diversity receivers.
