Abstract :
Most of GNSS use CDMA access technique, and apply various spreading modulation techniques to reduce inter-system interference. In this paper we present the research of CSS based spreading modulation technique. We generate transmit signal and analyze the correlation property. The side-peak magnitude is slightly larger than existing method, but we expect that the difference will have overcome by future receiver system and algorithms.
