Performance Analysis of a CDMA/PRMA-HS Protocol for LEO Satellite communication System

摘要

In this paper a new multiple access protocol CDMA/PRMA-HS for LEO constellation is present, which support mixed voke/data traffic. Voice terminals transmit packet with reservation mode and data terminals with random competing mode. This proposed scheme improves the capacity of system, and voice packet have higher priority to transmission. In this paper, the performance of protocol is analyzed in theory and is discussed with numerical value. Results indicate that this is a good protocol for integrating voice/data traffic.
