Incoherent demodulator matched filter

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 … WebDec 3, 2024 · The matched filter simply requires a precise sampling time at the output, however, surely so does the incoherent FSK demodulator? Matched filters do not require a locally-generated coherent (in phase and hence frequency lock) version of the mark and space signals like a correlation detector does, so why are they classed as coherent …

Neural net-based continuous phase modulation receivers

WebIn this paper a MIMO CPM receiver with an incoherent demodulation of the CPM signals is presented. Blind sig-nal separation (BSS) is applied in the MIMO CPM receiver to separate the transmitted signals. A carrier frequency mis-match in the receiver can be handled by the BSS. The BSS permits the demodulation of each separated signal by an in- WebWhen compared to other incoherent correlator systems currently being investigated, the standard Van der Lugt filter is simpler than the two-pupil system of Lohmann and Rhodes …

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. WebData filtering is used in digital demodulation to limit bandwidth and reduce intersymbol interference. This VSA includes several commonly used filter types and has the ability to apply user-defined filters. All filters are computed to 20 symbols in length by default. If the filter alpha is < 0.4, the VSA uses extended filter length (40 symbols ...
