Ultra-Wideband Communication Channel Modelling and Analyses

The problem statement is that existing ultra-wideband (UWB) communications operate within a range of 3.1 to 10 GHz, but there are difficulties in reducing the frequency. This necessitates the development of a UWB channel model to determine optimal parameters. The aim of this project is to create a model for a UWB communication system and compare its key parameters, such as the signal-to-noise ratio (SNR) and bit error rate (BER). Methods used include UWB modelling for different modulation schemes, including BPSK, QPSK, and QAM, as well as QAM16 and QAM64. A bit error coefficient analysis was also conducted, along with SNR analysis. Novelty. A mathematical model of an ultra-wideband channel has been proposed, and its diagram has been developed in the Simulink environment. Results. A UWB model was developed that can be used in further research. The evaluation of the model is based on two key parameters: BER and SNR, with QPSK being the most promising modulation scheme for UWB. The theoretical and practical significance of this research lies in evaluating key performance indicators and providing a basis for future development.
