Abstract

The subject of the study are the organization of wireless transmission of digital information based on ultra-wideband signals. The goal is the development of models and methods for organizing broadband wireless communications operating in difficult interference environments. The task is to ensure the stable and safe operation of communication systems. The methodology is based on the method of generating ultra-wideband digital signals and the method of extracting ultra-wideband information signals in the communication channel with interference. The methods used: methods of analytical, simulation and inverse Fourier transform. The following results are obtained. A technique has been developed for wireless transmission of digital information based on ultra-wideband signals, which includes a method for generating ultra-wideband information signals with code spectral modulation and a method for extracting information signals in a communication channel with interference. An assessment of the effect of interference on the quality of the information being restored is performed. A special class of intra-system interference has been identified, which appears due to the multiplicity of delays in the information bit stream T0 or T1. It is shown that their appearance leads to an increase in the bit error when extracting information signals in the communication channel. A mechanism is proposed for eliminating these errors by setting the multiple delays T0 and T1 when generating ultra-wideband information signals. Conclusions. The use of communication channels with an ultra-wide frequency band makes it possible to simultaneously implement a set of requirements for the electromagnetic compatibility of telecommunication systems, high-speed transmission of information with high noise immunity with respect to external interference.
