PSK Data Transmission for Use in Medium Wave Broadcasting Systems

摘要

Low Phase Dev/ation PSK (LPD-PSK) signal can be expressed combining the carrier power spectrum and sinX/X power spectrum. The carrier spectrum of the LPD-PSK signal is used for AM radio signal transmission, and the sinX/X spectrum is used for the digital code transmission respectively. The LPD-PSK signal sends the digital code with AM signal simultaneously. This paper describes the expression of LPD-PSK signal compare to Mth PSK signals.
