M.Sc. Tezi Görüntüleme
Computer modeling of satellite communications channels is a valuable adjunct to analytical modelling and hardware simulation for predicting and verifying communications link performance.
In the computer simulation approach, sampled signals are created in the computer and operated on by algorithms that simulate the effects of filtering, channel nonlinearities, interference, and noise. After passage through the simulated channel, the distorted signals are demodulated to determine the performance degradation introduced by the channel.
This thesis describes the approach used in simulating communications channels on the computer.
In the whole satellite system, digital system generated was passed through the elements of the channel and bit error rate (BER) was determined.
This developed algorithm is generalized in order to apply for the other satellite system.
