MATLAB Simulation of MSK Bit Error Rate with Matched Filter Implementation

This research conducts MATLAB simulation and analysis of Minimum Shift Keying (MSK) bit error rate performance with matched filter implementation. The study focuses on analyzing BER characteristics of MSK modulation technology through MATLAB simulation experiments, utilizing built-in communication toolbox functions and custom implementations. The research includes designing and optimizing matched filters using root-raised cosine filters and correlation-based receivers to enhance system performance. Key MATLAB functions employed include `berawgn` for theoretical BER calculations, `comm.MSKModulator` for signal generation, and custom matched filter design using `rcosdesign` function with appropriate roll-off factors. Through these investigations, we gain deeper understanding of MSK modulation techniques and provide practical guidance for real-world applications, including implementation approaches for improving receiver sensitivity and reducing inter-symbol interference.
