Peculiarities of Determining and Providing Throughput in Telecommunication Systems

The main requirements for telecommunication systems are its qualitative characteristics: transmission rate, bandwidth, bit error probability. These characteristics are in a complex interdependence, which necessitates research using special methods and MATLAB system. In the paper the proposed methods of analysis and synthesis of the system are employed, which allow to obtain optimal system characteristics. The expediency of use of bipolar signal transmission is emphasized. The value of the minimum and sufficient channel bandwidth to ensure the maximum signal rate is obtained. The advantages of using a multi-position signal, which provides either a reduction of channel bandwidth or increase of the system bandwidth at a given constant channel bandwidth are shown. Shannon’s formula was used to study the system frequency efficiency, which made it possible to propose a method of combined graphs for the system synthesis.
