Abstract
The presented research relates to the field solving the problem of increasing the efficiency transmission and noise immunity reception discrete messages used for the exchange traffic flows between communication systems and radio engineering complexes of entities. The object of the study is hardware and software systems and radio channels multiservice communication networks using multi-antenna technologies. Multi-antenna systems in multiservice communication networks allow increasing the capacity radio channels by transmitting a signal using several antennas on the transmitter side and several antennas on the receiver side. It is worth noting that the capacity of the radio channel is still limited due to the use of a power distribution algorithm. The efficiency and noise immunity indicators of the functioning of communication systems in the presence of interference sources are analyzed based on the architectural concept of the following and future public communication networks. The subject area is the problems applying a new approach to multiservice communication networks for optimal use resources end-to-end digital technology and modern wireless cellular communication technologies. The purpose of the study is to develop a new approach to constructing a method for calculating the evaluation of the characteristics of transmission efficiency and noise immunity when receiving traffic flow messages in a complex signal-noise environment. Based on the methods for calculating the evaluation of the performance indicators of multiservice communication networks, important analytical expressions for further research were obtained. As a result of the study, the main conclusions of the study were obtained, which can be implemented and used in multiservice stationary and wireless cellular networks to calculate the transmission efficiency and reception noise immunity indicators. The technical and economic effect for multiservice networks and radio engineering complexes consists in increasing their throughput by attracting funds and resources of modern cellular mobile network technologies. The substantiation proposed main stages of the study is provided, the results of the analytical study and simulation modeling are presented, confirming the validity of the theoretical conclusions made.
