Assuming that each input branch of an M-antenna selection combining system has equal SNR, πγπ, the output SNR was found to be πγ_SC=γ ∑ᵢ=1M 1iπ. (a) Using the following rela a) The output SNR increases with the number of antennas. b) The output SNR decreases with the number of antennas. c) The output SNR remains constant regardless of the number of antennas. d) The output SNR is unrelated to the number of antennas.
