description: The object of research is the software part of the UWB signal receiver. The purpose of the work is the development and implementation by the program of the UWB part of the receiver on the STM32G474RE microcontroller. The work provides a brief overview of UWB signals, modulation methods and the UWB receiver block diagram itself. When studying the reference manual and the technical specification of the MC, a serial peripheral interface SPI was selected for receiving pulses, two timer channels were also used for clocking the slave device and for asynchronous reset of the receiver trigger. An algorithm was implemented that increases the noise immunity of reception by increasing the clock frequency of the SPI relative to the pulse transmission frequency. The data message was received using two SPI interfaces, a receiver, and a transmitter. The necessary signals were generated using programmable timer channels in PWM mode. The results obtained, given at the end of the second section, can be used for UWB systems by changing the synchronization frequency of SPI and using transmitted pulses of the order of fractions of nanoseconds.The novelty of the developed software part lies in the use of a modern element base in the form of an STM32 microcontroller, as well as a special ratio between the synchronization frequency and the pulse transmission frequency.
