Abstract
SMATV (satellite master antenna television) systems can be considered as an optimal distribution network for a fast and effective introduction of digital TV to the end users in several European countries and is an alternative in those which can be used countries their that are developing infrastructures. This paper studies the performance of digital collective systems in the presence of a noisy phase reference (phase noise) and a noisy clock reference (clock jitter). For this purpose, an attempt has been made to characterize the performance of this digital transmission system through the bit error rate (BER) or symbol error rate (SER) as a function of the Eb/No ratio. The Eb/No ratio has been parametrised by phase noise and clock jitter, obtained through computer simulations. It is shown that these effects produce a significant increase in the BER/SER performance. The simulator used was the SPW (Signal Processing WorkSystem) by means of which the BER/SER has been estimated using a quasianalytical (semianalytic) approach and the Monte Carlo method, so that the results can be compared and checked.
