Název v původním jazyce
Joint Estimator for Acquisition of GNSS Primary and Secondary Code with Pre-correlation Coherent Accumulation
Popis výsledku v původním jazyce
Objective of this contribution is the acquisition algorithm for modern GNSS signals containing secondary codes. This algorithm is usable for a hardware based GNSS signal acquisition unit using the parallel code search (PCS) algorithm. The contribution deals with standard post-correlation methods and focuses on a comparison of methods based on a pre-correlation accumulation of the signal by the Pre-correlation Coherent Accumulation principle (PCA). The aim is a comparison of properties of different types of used zero-padding methods in both pre and post correlation approaches. An extension of a coherent time in front of a PCS-FFT algorithm based unit by help of a pre-correlation processing could considerably reduce a required minimal latency of FFT blocks. A latency time equal to one period of primary code for the post-correlation combining is replaced for a proposed algorithm to a much longer time equal to a period of the secondary code.
