MATLAB Simulation of UWB Transmitter (TX) and Receiver (RX) Using BPSK Modulation and Demodulation

This simulation uses MATLAB to implement Ultra-Wideband (UWB) communication with Binary Phase Shift Keying (BPSK) modulation and demodulation for both transmitter (TX) and receiver (RX) functionality. At the transmitter side, digital data is encoded into baseband signals using BPSK modulation, where binary '0' and '1' are represented by phase shifts of 0 and 180 degrees respectively. The modulated signal is then transmitted through the UWB channel using impulse radio techniques, typically involving short-duration pulses with wide bandwidth. At the receiver side, the system performs BPSK demodulation to decode the received signal back to the original data. This involves coherent detection using correlation receivers or matched filters to detect phase changes in the incoming signal. The implementation typically includes synchronization algorithms for timing recovery and error correction mechanisms to handle channel impairments. Key MATLAB functions used in this simulation may include: - pskmod() and pskdemod() for BPSK modulation and demodulation - Pulse shaping functions like rectpuls() for UWB pulse generation - awgn() function to add Gaussian noise for channel modeling - Correlation detection algorithms for signal recovery - BER calculation functions for performance analysis This approach enables reliable data transmission in UWB communication systems by leveraging the noise immunity of BPSK modulation and the multipath resistance of UWB technology. The simulation provides a comprehensive framework for analyzing system performance under various channel conditions and parameter settings.
