Fixed modulation
WebFor large input SNR and a fixed modulation index, the output SNR is directly proportional to the input SNR. When the input SNR << 1, the envelope signal is primarily dominated by the envelope of the noise signal and the modulating signal is badly mutilated. Under this circumstance, it is meaningless to talk about output SNR. The loss WebJun 25, 2024 · Modulation schemes map digital values (zeroes and ones) onto an unreliable medium.
