Influence of propagation characteristics and repeaters on the performance of a multiple link teletext system
Abstract
A general method of system analysis is presented, and used for the determination of the error probability function for any given situation, including propagation or equipment anomalies. The method is also employed to determine the relationship between the mentioned anomalies and the variations in the signal to noise ratios. Two examples of teletext transmission simulation are given, one assuming ideal propagation conditions and the other assuming a 250 KHz detuning, in both from 14 dB down to an error probability of 10 to the minus 8th power.
