Abstract
The performance of a satellite systems depend on the propagation mode of the radio waves. The nature of satellite channel is one of the biggest obstacle facing the design of communications systems. This characterised satellite channels by fading and interference. Moreover, satellite communication systems are limited by available transmitting power and bandwidth. Signal power could be reduced while maintaining the same quality of service (QoS). This can be achieved by channel encoder techniques using forward error correction (FEC). Turbo codes is one of the efficient error control codes currently available. The combination of turbo codes and code division multiple access (CDMA) could improve the system performance especially in a multiuser environment. This paper presents the simulation results of turbo codes and CDMA performance on mobile satellite communication channels.
