Digital matched filter detection of GMSK/DS/SS signal

摘要

In this paper, the constant envelope spread spectrum modulation system for applying OQPSK type demodulation by digital correlator is examined. The spread spectrum modulation by the GMSK modulation system of OQPSK type in which the IQ axis independently modulates the data is proposed, and the relationship between the correlation characteristic and the BT product of the GMSK and BER characteristics is investigated.
