A computing method of the error probability in 4PSK transmitting systems under selective fading condition
Abstract
A method for computing the error probability in 4PSK systems which is easier to implement and shorter to compute than the GramCharlier series expansion previously proposed, is described. The method is applicable when the interference amplitude after each pulse vanishes in a time interval shorter than 10 pulse to pulse periods. Models for the complex demodulated signal and for the transfer function of the multipath transmission are presented. A step by step calculation procedure is described and the implementation of the algorithm is discussed. An application example shows that the probability is computed with a 2% precision in one tenth of the time required for the GramChartier series to start convergence.
