Knowledge and Implementation of BOC Modulation

This article explores Binary Offset Carrier (BOC) modulation implementation in MATLAB, providing original code for reference and educational purposes. BOC modulation technology is widely adopted in Global Navigation Satellite Systems (GNSS) to enhance signal robustness and improve positioning accuracy. The implementation includes code for generating BOC-modulated signals using MATLAB's built-in functions for waveform synthesis and correlation processing. Key algorithms involve subcarrier modulation techniques where a PRN (Pseudo-Random Noise) code is multiplied with a square wave subcarrier, typically implemented using MATLAB's array operations and signal processing工具箱. Applications span wireless communications, radar systems, geodetic surveys, and navigation positioning. The article details BOC modulation principles, characteristics, and practical applications, along with MATLAB simulation methodologies involving signal generation, spectrum analysis using FFT functions, and performance evaluation through correlation peak analysis. This resource benefits students studying BOC modulation while providing valuable references for engineers and researchers in related fields.
