Method and device for l5 direct acquisition and nh bit synchronization

A user equipment (UE) comprising:

• an input sample memory (ISM) configured to store data from a memory, wherein the data corresponds to input from an L5 antenna of the UE;
• a first high-resolution correlation (HRC) engine configured to perform coherent correlation and accumulation on the data for at least one code-frequency offset combination, to generate coherent correlation results;
• and
• a second HRC engine configured to process 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.

A user equipment (UE) comprising:

• a processor;
• and
• a non-transitory computer readable storage medium storing instructions that, when executed, cause the processor to:
• load data from a memory to an input sample memory (ISM) of the UE, wherein the data corresponds to input from an L5 antenna of the UE;
• perform, by a first high-resolution correlation (HRC) engine of the UE, coherent correlation and accumulation on the data for at least one code-frequency offset combination, to generate coherent correlation results;
• and
• process, by a second HRC engine of the UE, 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.
