Comparative Analysis of Two Phase Modulation Methods

This paper presents a comprehensive analysis and comparison of two phase modulation methods. We begin by introducing the fundamental principles and implementation approaches of both techniques, then conduct detailed comparisons across multiple dimensions including performance metrics, application scope, and computational complexity. Through MATLAB programming implementations, we demonstrate the distinctions and interrelationships between these methods, examining their behavior under various conditions and highlighting their respective advantages and limitations. The comparative analysis includes spectral efficiency evaluations using FFT algorithms, bit error rate (BER) simulations with different signal-to-noise ratios, and computational complexity assessments through time-domain signal processing functions. Furthermore, we discuss optimization strategies and future development directions for both modulation schemes. This systematic comparison provides readers with thorough understanding of both phase modulation methods, offering valuable guidance and insights for their practical applications and research advancements.
