Capacity enhancement of Web traffic in W-CDMA mobile satellite systems

We attempt to enhance the Web traffic capacity of third generation (3G) W-CDMA land mobile satellite communication systems. The aim of the capacity analysis is first to analyze the effect of power control errors (PCEs) which are expected to degrade the performance of mobile satellite systems severely (see Hijres Alsuwaidi, J. and Mahmoud, S.A., 2001). Secondly, the use of macrodiversity, as proposed to mitigate the effect of power control errors (see Hijres Alsuwaidi and Mahmoud, Globecom, 2002), is shown to be a very powerful method to enhance the Web traffic capacity of multi-beam GEO and MEO mobile satellite systems. Numerical results indicate that macrodiversity may be considered as an essential component to enhance Web traffic capacity of power limited 3G mobile satellite systems, hence lowering the channel operation cost which can be considered as the main challenge in deploying 3G mobile satellite systems.
