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.

Hi all, In studying receivers architectures and demodulation techniques for many types of modulations, I am facing with a doubt about about matched filters, with impulse response h(t) = p(−t) h ( t) = p ( − t) where p(t) p ( t) is the modulating pulse. The question arise from an homework but mine doubt is related with ...
In signal processing, a matched filter is obtained by correlating a known delayed signal, or template, with an unknown signal to detect the presence of the template in the unknown signal. This is equivalent to convolving the unknown signal with a conjugated time-reversed version of the template. The matched filter is the optimal linear filter for maximizing the signal-to-noise ratio (SNR) in the presence of additive stochastic noise. WebFor MSK, three demodulators are compared. The first demodulation algorithm, partially coherent demodulation, is based on a classical matched filter approach combined with …
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].
