ENHANCING SEARCH CAPACITY OF GLOBAL NAVIGATION SATELLITE SYSTEM (GNSS) RECEIVERS |
摘要 |
Enhancing search capacity of Global Navigation Satellite System (GNSS) receivers. A method for searching satellite signals in a receiver includes performing a plurality of searches sequentially. The method also includes storing a result from each search of the plurality of searches in a consecutive section of a memory. Further, the method includes detecting free sections in the memory. The method also includes concatenating the free sections in the memory to yield a concatenated free section. Moreover, the method includes allocating the concatenated free section for performing an additional search. |

1. A process of searching satellite signals from a plurality of satellites in a global navigation satellite system receiver, comprising:
allocating a plurality of sections of a memory for a plurality of searches, each search of the plurality of searches being a 3-dimensional search, the 3-dimensional search comprising searching for a code for all code phases for one Doppler hypothesis, the code corresponding to a satellite; performing the plurality of searches sequentially; storing a result from each search of the plurality of searches in a corresponding allocated section of the plurality of sections of the memory; detecting at least one of termination of at least one group of code phase searches for a particular search in the plurality of searches, and termination of all code phases for the particular search from the plurality of searches; detecting free sections in the memory based on detecting termination; concatenating the free sections to yield a concatenated free section if the free sections, in conjunction, are sufficient for performing an additional search; and allocating the concatenated free section for performing the additional search. |
