Direct Sequence Spread Spectrum Ultra-Wideband (DSSS-UWB) Simulink Simulation

This documentation presents a comprehensive Simulink-based simulation for Direct Sequence Spread Spectrum Ultra-Wideband (DSSS-UWB) systems. The simulation model was independently designed and developed from scratch, ensuring complete originality in both architecture and implementation. Key components include a DSSS transmitter with pseudo-random sequence generation and BPSK modulation, a multipath UWB channel model with AWGN integration, and a correlation-based receiver with synchronization and despreading algorithms. Through this simulation platform, I conduct performance analysis and characteristic studies of DSSS-UWB technology under various operational conditions. The model enables parameterized testing of different spreading factors, data rates, and signal-to-noise ratios to evaluate system robustness. Implementation features include configurable simulation parameters, real-time signal visualization blocks, and BER performance monitoring modules. This simulation framework provides valuable insights into DSSS-UWB operating principles and practical applications. It serves as an effective tool for system optimization, performance validation, and educational demonstration, offering significant guidance and reference for real-world engineering implementations. The modular design allows easy extension for additional features like adaptive equalization or advanced modulation schemes.
