Research output: Contribution to journalConference articlepeer-review


Chirp modulation is one of the proposed digital phase modulation schemes where positive and negative data are represented, respectively, by increasing and decreasing of the instantaneous frequency. Chirp modulation is resistive to Doppler effect while its error performance, due to the phase characteristics, is quite poor. The presentation deals with a generalization of the Chirp technique leading to new classes of signal formats for digital communications with improved spectral efficiency and good error performance. For this, the instantaneous value of modulated signal frequency is gained from the second time integral of the information carrying data signal. Further, for a generation of specific signal formats, the different modulating signal pulse shaping with partial response technique is applied.
