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.
Why is MRC better than SC?
Maximal ratio combining (MRC) technique is known to give a better SNR gain than selection combining (SC) technique. This improved performance of MRC comes at the cost of multiple receiver chains which implies increased receiver complexity and cost.
What is maximum ratio combining in MIMO?
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 selective combining?
In selection combining, the received signal from the antenna that experiences the highest SNR (i.e, the strongest signal from N received signals) is chosen for processing at the receiver (Figure 1). That is, the weight of the path that has the highest. is chosen.
