Стаття присвячена дослідженню впливу основних технічних параметрів базової станції (БС) на
ймовірність бітової помилки, співвідношення сигнал/шум на вході приймача мобільної станції (МС) при відповідній
швидкості передачі цифрового потоку. Наводяться розрахункові формули для визначення необхідної відстані між
базовою станцією та мобільним терміналом залежно від заданої ймовірності бітової помилки та потужності
сигналу на вході приймача.
The development of wireless technologies has allowed users to have a connection anywhere in the world. The growth of advances in research and development of wireless communication technologies, the increasing capacity of electronic devices contribute to the spread of services for mobile users. Wireless networks are becoming more interactive, which contributes to the paradigm shift to new generations of mobile networks where continuous mobility in heterogeneous networks is the basic principle. The article is devoted research of influence of speed of data transmission in a cellular mobile radio system with code division of channels in appropriate ratios of signal/noise at the input of the receiver the probability of bit error and finding the maximum number of active subscribers in the cell. The influence of the basic technical parameters of the base station (BS) on the probability of a bit error rate, the signal/noise ratio at the input of the receiver of the mobile station (MS) at the appropriate digital transmission rate. The calculation for mulasare used to determine the required distance between the base station and the mobile terminal, depending on the given probability of the biterr or rate and the signals trength of the receiver input. The probability of a bit error rate in the systems of the mobile communication with the phase modulation of the BPSK and the energy expended on the transmission of one bitis calculated. The paper describes the application of errorcorrecting modulation techniques, effective systems balatonring access to distribution channels, reduce system noise internally. Calculation formulas for determining the signaltonoise ratio at any point in mobile communications and also to control the degree of change of this relationship when moving mobile station.
