WebThe Matched Filter To motivate this linear processor, let us start with a very simple sequential communication scheme: we send independent information bits at diﬁerent time instants, butinterleave L¡1 zeros between every information bit. In other words, we send information only once inL time samples. WebApr 29, 2024 · In the simplest case, a sine wave of unknown amplitude, in noise, is demodulated by multiplying by a reference sine wave of known amplitude, with the same frequency and phase as the noisy sine wave. Then the difference frequency is at DC, so the DC magnitude is proportional to the noisy sine wave’s amplitude.
