A MODEL OF THE COLLISION ASYNCHRONOUS COMMUNICATION CHANNEL

Karel Burda

   This paper deals with the collision asynchronous communication channel. An unslotted ALOHA channel and a Frequency-Hopped Spread-Spectrum Multiple-Access System channel appertain to the category of the collision asynchronous communication channels. In this paper the method for the computation of the probability distribution of erasures or errors in received symbol block is presented. This distribution allows to analyze the influence of code measures on parameters of collision asynchronous communication systems. The analysis of the influence of selected code measures on the performance of a Slow Frequency-Hopped Spread-Spectrum Multiple-Access System is showed as an example.

Keywords: asynchronous communication, probability distribution of erasures and errors, code measures
