Generalized chirp modulation technique

Research output: Contribution to journalArticle

Abstract

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 paper 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. To achieve this task, the second time derivative of an information carrying phase component of a modulated signal is set to be proportional to an information carrying data signal. Further, for a generation of specific signal formats, the alternate mark inversion encoding of data to be transmitted is applied.
