Simulation and Power Spectral Density Analysis of Time-Hopping Ultra-Wideband

This source code provides simulation and power spectral density analysis for time-hopping ultra-wideband (TH-UWB) systems, forming the foundation for ultra-wideband research. Ultra-wideband is a wireless communication technology known for its advantages including high transmission speed, strong penetration capability, and excellent interference resistance. UWB technology finds extensive applications in both military and civilian fields. The code implements fundamental methodologies for analyzing TH-UWB power spectral density, featuring algorithms for generating pseudo-random time-hopping sequences and calculating spectral characteristics using periodogram estimation techniques. Key functions include pulse waveform generation, time-hopping modulation implementation, and spectral analysis through Fast Fourier Transform (FFT) operations. This foundational approach enables researchers to study UWB transmission performance, channel characteristics, and signal propagation behavior under various conditions. The implementation provides configurable parameters for pulse shaping, hopping patterns, and spectral analysis resolution, allowing for flexible investigation of UWB system properties through numerical simulation approaches.
