Detection of FSK signals using linear FM dispersion method

A new signal processing technique for the detection of FSK signals in white Gaussian noise is presented. The new feature of this technique is that the received FSK signal waveforms are first converted into new waveforms and the detection is carried out by using an appropriate matched filter matched to the new waveforms. The waveform conversion approach at the receiver is advantageous since the required matched filter for the new waveform is realizable more readily than that for the FSK waveforms.
