Abstract :
To mitigate the main impairments due to the mobile satellite channel, satellite systems adopting code-division multiple access (CDMA) can exploit diversity. Each signal can flow through more than one path, increasing link availability or improving signal-to-noise ratio (SNR). This letter presents a general mobile satellite channel model for an arbitrary diversity order assuming that all the links are statistically independent. A diversity availability improvement upper bound is calculated.
