Comprehensive MATLAB Simulation Program for CPM Continuous Phase Modulation Systems

This documentation presents a comprehensive MATLAB simulation program for Continuous Phase Modulation (CPM) systems. The simulation framework enables thorough investigation of CPM system performance characteristics and operational principles. Through this program, users can simulate various CPM configurations and analyze their behavior by modifying key parameters such as modulation index, pulse shape, and memory length. The implementation includes core MATLAB functions for: - CPM signal generation using phase trajectory computation - Modulation index variation studies with smooth phase transitions - Pulse shaping filter implementation (e.g., rectangular, raised-cosine) - Eye diagram and phase tree visualization algorithms - Bit error rate (BER) performance evaluation under different channel conditions The code structure utilizes MATLAB's communication toolbox components while implementing custom algorithms for phase state machine management and continuous phase calculation. Key functions handle symbol mapping, phase accumulation, and complex baseband signal generation with proper sampling rate considerations. Additional resources and reference materials are provided to support further exploration of CPM system concepts, including advanced topics like partial response signaling and optimal detection techniques. This expanded documentation aims to facilitate deeper understanding and practical application of CPM systems through hands-on simulation experience.
