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 equal gain combining?
Equal-gain combining: All the received signals are summed coherently. Maximal-ratio combining is often used in large phased-array systems: The received signals are weighted with respect to their SNR and then summed. The resulting SNR yields where is SNR of the received signal .
What is selection combining technique in wireless communication?
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.
What is selection diversity?
Selection diversity approach is one way out – With selection diversity, the receiver selects the antenna with the highest received signal power and ignore observations from the other antennas. The chosen receive antenna is one which gives .
