In this paper, we constructed an ultra-wideband communication system based on linear frequency modulation signal, and studied its key technologies and performance. Firstly, we introduced the principle and structure of the system, including the functions and implementation principles of each module such as transmitter, channel and receiver. Then, we analyzed the key technologies of signal processing, data modulation and radio frequency frontend in detail, so as to improve the reliability, anti-interference ability and decoding efficiency of the system. Finally, we constructed an ultra-wideband communication system model on the Matlab platform, and verified the performance of the system through simulation experiments, including transmission rate, bit error rate and signal-to-noise ratio. Simulation results show that the ultra-wideband communication system constructed in this paper performs well in all performance indicators and has practical value. Keywords: ultra-wideband communication system, linear frequency modulation signal, key technologies, performance simulation.
