A study of non-coherent digital matched filters (DMF's) with multibit quantizers, matched to phase-shift-keyed signals, is presented. Results relating output and input signal-to-noise ratios are given for three types of additive channel interference and mixtures thereof: white Gaussian noise and incoherent and coherent constantamplitude sine-wave jamming. These results are compared with both analog filter results and computer simulation runs obtained previously.
