WebIt is shown that the standard Van der Lugt filter can be used as an incoherent processor if appropriate modifications are made to its amplitude point-spread functions. In the proposed system the problems associated with realizing bipolar impulse responses are shifted to electrooptic detection of the desired signal on a constant bias level. When compared to … 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.
