This work addresses the evaluation and design of pilot channels employing Serial Bicode DSSS to improve GNSS receiver synchronization. While the bicode concept itself is introduced elsewhere, the core contribution of the thesis is a statistical framework for analyzing both acquisition performance—via long non-coherent integration—and block transition detection. The framework quantifies false alarm and missed detection probabilities under various demodulation schemes, providing a comprehensive view of synchronization trade-offs. A design methodology is then proposed for constructing pilot channels that optimize performance based on mission requirements. Simulation results confirm the effectiveness of the derived framework, highlighting its potential to reduce time-to-first-fix.
