Incoherent demodulator matched filter

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. WebIncoherent demodulation is a significantly harder problem than coherent demodulation. The signal can no longer be characterized by a finite set of states, resulting in a cum- bersome theoretical formulation that requires the calculation of expectation integrals with respect to the unknown signal phase [5].

WebWith coherent integration we insert a coherent integrator, or signal processor, between the matched filter and amplitude detector as shown in Figure 1. The signal processor samples the return from each transmit pulse at a spacing equal to the range resolution of the radar set and adds the returns from N pulses. 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.
