MATLAB Simulation of DS-BPSK Ultra-Wideband Communication System Performance (DS-UWB Transmit Signal)

This project implements MATLAB simulations to investigate the performance of DS-BPSK (Direct Sequence Binary Phase Shift Keying) Ultra-Wideband communication systems, with particular emphasis on DS-UWB transmit signal generation. The simulation framework involves generating pseudorandom spreading sequences, implementing BPSK modulation, and creating UWB pulse waveforms using functions like randi() for sequence generation and square-root raised cosine pulses for pulse shaping. Through systematic simulation experiments, we can analyze the system's performance under various parameter configurations, including different spreading factors, pulse shaping parameters, and signal-to-noise ratio conditions. The results provide valuable insights for system design optimization, demonstrating key implementation aspects such as correlation properties of spreading codes, power spectral density characteristics, and BER (Bit Error Rate) performance evaluation using Monte Carlo simulation techniques.
