MATLAB Simulation of BPSK Baseband Transmission System

This article demonstrates how to implement a BPSK (Binary Phase Shift Keying) baseband transmission system simulation using MATLAB. We will progressively build key system components including binary data source generation, BPSK modulation using phase shifting techniques, transmit and receive filter design (typically employing raised-cosine filters), sampling mechanisms, equalization algorithms (such as LMS adaptive equalizers), signal detection methods, BPSK demodulation with phase comparison, and information recovery output. The implementation will utilize MATLAB's communication toolbox functions like pskmod() for modulation and awgn() for channel modeling. Additionally, we will generate Bit Error Rate (BER) curves through Monte Carlo simulation to comprehensively evaluate system performance under varying SNR conditions. Through this guided implementation, you will gain detailed understanding of BPSK baseband transmission simulation processes and deep insights into each module's functionality and implementation approaches.
