Abstract: A method and an apparatus are provided in which data is loaded from a memory to an input sample memory (ISM) of a user equipment (UE). The data corresponds to input from an L5 antenna of the UE. A first high-resolution correlation (HRC) engine of the UE performs coherent correlation and accumulation on the data for at least one code-frequency offset combination, to generate coherent correlation results. A second HRC engine of the UE processes the coherent correlation results by at least performing frequency widening and non-coherent accumulation to generate non-coherent correlation results indicating at least peak accumulations of correlations.
