The subject of study is the process of providing wireless noise-resistant transmission of discrete information that are based ultra-wideband signals with high capacity for information transmission. Goal of the study – development of analytical expressions for calculating the probability of bit-errors depending on the signal-to-noise ratio in the channel with additive Gauss interference. The objective is to ensure stable and reliable performance of UWB communication system under mush circumstances. Methods used: methods of analytical simulation and digital signal coding. The followings results are obtained. Based on analysis of the operation of the UWB ratio communication system revealed that the change in energy and autocorrelation function of received signals in the stream of information bits are the cause of intra-system interference that further causes an increase sn bit error and degradation of the probabilistic characteristics of communication systems. Revealed analytical relationship allow us to calculate the probability dependence of occurring errors per bit depending on the signal-to-noise ratio or at different base signal values. Revealed the existence of local extremums for bit error characteristics at optimal UWB base values signals when the probability of a bit error becomes the smallest. That allows us to reasonably choose the best value of the UWB signal base and have high noise immunity and reliability of the digital information transmission system. Conclusion. Using UWB signal technology allows wireless covert transmission of information with low radiation power at a speed of 1-2 Mb / s with error occurrence probability per bit at the level of 10-4 - 10-6 when the signal-to-noise ratio is significantly less than one. Thus, a UWB radio system with a code modulation at the transmitter and spectral processing at the receiver has higs noise smmunity, which allows reliable transmission of digital information in an interfering environmentDownloads
