What are the advantages of maximal ratio combining over selection combining?

Each technique has its own unique advantage but in comparison to other diversity techniques, maximum ratio combining technique is superior to other in many aspects. The MRC technique has high diversity gain and high signal to noise ratio compared to other diversity techniques.

What is maximal ratio combining technique?

In telecommunications, maximum-ratio combining (MRC) is a method of diversity combining in which: the signals from each channel are added together, the gain of each channel is made proportional to the rms signal level and inversely proportional to the mean square noise level in that channel.

What is MRC in MIMO?

MIMO Multiple Input Multiple Output. MISO Multiple-Input Single Output. MRC Maximum Ratio Combining.

Why diversity combining schemes provide such an improved performance over no diversity?

Diversity combining reduces one possible single-point failure: any single receiver failure, or local interference to a single receiver, will not block reception on the entire system. Equipment sites can host many radio transmitters and receivers. A single site is subject to local, site-specific interfering signals.
