The necessity of increasing the efficiency of digital telecommunication systems or networks is due to the continuous increase of data volumes transmitted by such systems or networks. This task can be solved by optimizing a number of system or network parameters based on the adoption of certain compromises. To make the right decision, we need to know the impact of each parameter of telecommunication system or network on their efficiency. Recently, a lot of attention is focused on this issue [1-6]. However, the development of complex indicators to detect the influence of the parameters of a digital telecommunication system or network on their efficiency remains an actual task. The purpose of this work is to study the influence of parameters of digital telecommunication system or network on their technical efficiency through the use of a complex indicator. Basic parameters of the digital telecommunication system, which influence on its efficiency Let's consider the basic parameters of the digital telecommunication system, which influence on its efficiency. Among them, the most important are the data rate, the ratio of the energy of one data bit to the power spectral density of the white noise and the system throughput. The data rate Vb (bps) is: (1) Vb [...]
