International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, California / This paper presents one new type CDMA multi-signal receiving protocol, which is suitable for satellite mobile communication systems. Then it gives the principle analysis and describes the realization of this protocol. Meanwhile, it gives the software protocol implementation scheme. From the long point of view, it will more increase the system flexibility, which is easier to update; and will solve the interoperability and integration application problems. Finally, the simulation results conclude that software implementation of CDMA multi-signal receiving in satellite mobile communication system is feasible, and it may be used in other wireless communication systems.
