Abstract
As an important branch in the field of electronic information engineering, ultra-wideband wireless communication technology has been paid wide attention in recent years because of its advantages of high data transmission rate, low power consumption and strong anti-interference ability. This study centered on UWB wireless communication technology, to explore its performance optimization and practical application potential in complex electromagnetic environment. By analyzing the demands and challenges of modern communication system, combining the wide band characteristics and multi-path propagation advantages, a signal transmission scheme based on improved pulse modulation is proposed to improve the system capacity and spectrum utilization. The theoretical modeling and simulation experiments are used to construct an UWB system model suitable for short-distance high-speed communication scenarios and optimize the key parameters. The experimental results show that the proposed scheme can maintain high data transmission quality under SNR constraints while significantly reducing energy consumption. In addition, this study introduced a hybrid algorithm to enhance the robustness of the system for the lack of positioning accuracy and security.
