BER Analysis of BPSK Modulation in Ultra-Wideband Communication Systems

This report presents a comprehensive MATLAB implementation for analyzing the Bit Error Rate (BER) performance of Binary Phase Shift Keying (BPSK) modulation in Ultra-Wideband (UWB) communication systems. The implementation includes detailed explanations of modulation techniques and key concepts such as Additive White Gaussian Noise (AWGN). For realistic system simulation, AWGN is incorporated using MATLAB's built-in communication toolbox functions, where noise power is calculated based on the signal-to-noise ratio (SNR) specifications. The simulation employs BPSK modulation/demodulation algorithms and BER calculation methodologies using bit-by-bit comparison techniques. The analysis generates comprehensive time-domain waveforms showing modulated signals, noise effects, and received signals, along with frequency-domain representations obtained through Fast Fourier Transform (FFT) implementations. These graphical outputs facilitate deeper understanding of UWB communication principles and performance characteristics under various noise conditions. The report also explores system optimization strategies, proposing potential enhancements such as adaptive filtering techniques and error correction coding implementations. Through this MATLAB-based approach, readers gain practical insights into UWB communication technology and learn systematic simulation and analysis methodologies for wireless communication systems.
