MATLAB Simulation of Matched Filter

In this article, we provide a detailed explanation of implementing matched filter simulation using MATLAB. Starting from source waveform encoding, we simulate the entire communication chain including channel transmission and receiver decoding processes. Through this simulation experiment, readers can better comprehend the working principles of matched filters and gain deeper insights into fundamental signal processing concepts. The implementation involves generating modulated signals using functions like pulse shaping, adding channel effects with awgn for noise simulation, and designing the matched filter using correlation-based approaches with conv or xcorr functions. We also introduce essential MATLAB syntax and signal processing functions such as filter design tools and bit error rate calculation methods, demonstrating practical techniques for signal analysis and visualization. This article aims to help readers strengthen their foundational knowledge in both MATLAB programming and digital signal processing principles through hands-on implementation examples.
