MATLAB-Based GPS Signal Simulation Source Code

In this article, we demonstrate how to implement GPS signal simulation through programming in MATLAB. To achieve this objective, we follow these key implementation steps: 1. Generation and spread spectrum modulation of C/A codes using MATLAB's digital signal processing functions to create Gold codes with proper chip sequence generation. 2. Correlation analysis of C/A codes implemented through cross-correlation algorithms to evaluate code orthogonality and performance characteristics. 3. Generation and spread spectrum modulation of P-codes employing longer PRN sequences with precise timing control for enhanced security applications. 4. Correlation analysis of P-codes using advanced correlation techniques to assess their superior autocorrelation and cross-correlation properties. Through these implemented steps, we successfully simulate GPS signals and obtain clear, analyzable results. Our complete and well-documented code is straightforward to understand and can be executed directly in MATLAB environment. If you're interested in GPS signal simulation, this article provides an excellent starting point with practical code examples that demonstrate fundamental GPS signal processing concepts.
