Detailed Documentation
In this paper, we utilize fGenerateNavigationData.m to generate navigation data messages, employ mls_generator.m to create spreading pseudo-random codes (using maximum length sequences for signal spreading), and implement BOC (Binary Offset Carrier) modulation through boc_edit.m (general BOC implementation) and boc_5_28.m (specific BOC(5,2.8) modulation). These tools and methodologies are crucial for navigation system implementation as they enable the generation of precise navigation signals and facilitate efficient modulation processes. The BOC modulation specifically involves multiplying the carrier signal with a square wave subcarrier to create split-spectrum characteristics, improving spectral efficiency and multipath resistance in satellite navigation systems.
