In future years, satellites will continue to becommercially viable media for telecommunications only if systemsdesigners take account of the unique features that satellites have tooffer.

Propagation,ory can be applied to predict signal variations in the presence of the observed transmission factors. The Chapter begins by consideration of propagation effects experienced for fixed services. The effects of rain attenuation on propagation at high frequencies is explored and a statistical model for

Error Control Coding,e error performance of these modulation techniques in the presence of noise could be improved only by increasing signal power. As the signal power is at a premium in satellite systems, this approach is not practical. Error control coding is a branch of communications which deals with reliable transm
