PARAMETERS OF A NON-SYNCHRONOUS, RANDOM ACCESS, DISCRETE ADDRESS COMMUNICATIONS SYSTEM
Abstract
The parameters governing a non-synchronous communication system which uses discrete address and random access were evaluated for two types of discrete addressing. These types are: (1) time division and (2) time and frequency division. A brief discussion of a random access system using continuous wave transmission is also included. These various methods of addressing were evaluated from the viewpoint of subscriber activit as a function of error rate and the number of subscribers which a particular bandwidth can sustain. For discrete values of error rate, it is shown that the amount of bandwidth necessary increases as a function of subscriber activity. Therefore, it may be noted that for the types of discrete addressing which are under consideration, it will be necessary to use transmitters in the kilo-megacycle range if the number of subscribers is to be large, i.e., on the order of 30 or more.
