Hi ,
I am doing a project on MIMO (Multiple Input Multiple Output), which involves use of multiple transmitter and multiple receiver antennas for transmission and reception of a single signal.
In this method there is a technique which is called selection combining. In this technique the receiver scans all the receiver antennas and picks the antenna which has the best SNR. Can anyone please tell me that how do the receiver find out the SNR of a given signal?
The most obvious technique that came to my mind is to send pilot symbols which receiver already knows and thus determine the SNR by comparing the received symbols and transmitted symbols.
Is this how SNR is determined or it is something else?
Any help will be really grateful; thanks in advance!
