INTELLIGENT WIRELESS COMMUNICATION SYSTEM

Abstract

The subject of the study is models and methods for organizing a semantic communication system to increase the throughput of a wireless communication system. The goal is to develop recommendations for the implementation of multiple access with the distribution of information space according to the model. The development is based on artificial intelligence technology, which allows us to extract general and personalized semantic information from the multidimensional semantic space separately, allowing the communication system to move from the traditional transmission of information bits to the transmission of a model. The task is to ensure stable and reliable operation of a wireless network with an extended communication channel bandwidth. Methods used: methods of analytical modeling and time-position pulse coding. The following results were obtained. It is shown that in order to ensure the high quality of the wireless network, it is necessary to expand its bandwidth, which is limited by the physical resource of the radio frequency spectrum. It is proposed to overcome this contradiction by applying the technology of multiple access with distribution over the model. In this case, the information signal is emitted to the base station without a carrier frequency simultaneously in the entire frequency band, provided that the signal level is lower than the noise level. In this case, the method of positional-time coding is used, in which each information bit is encoded by hundreds of ultra-short chip pulses arriving in a certain sequence. In such wireless communication systems, the use of autocorrelation reception of modulated ultra-wideband signals is proposed. At the same time, the best reliability and noise immunity is provided by a wireless network using the time separation of the reference and information signals. Conclusions. Semantic communication systems with autocorrelation reception and separate transmission of reference and information signals provide an increase in the bandwidth of a wireless communication system, a high level of structural signal concealment, and reliable transmission of digital information, especially in conditions of interference.
