The Application of Cyclic Correlation Matched Filtering on Time-Phase Modulation

Abstract

The paper provides a new modulation method, time-phase modulation (TPM), with the rapid sideband attenuation based on abrupt phase change, in view of the spectrum spread in the traditional digital modulation methods as a result of slow sideband attenuation. A cyclic correlation matched filtering method is proposed with the spectral correlation theory for the cyclostationary characteristic of TPM. The simulation results show that the new filtering method can prove the reliability of TPM system compared to the traditional matched filtering method.
