POSITION LOCATION IN MEMORY LIMITED ENVIRONMENT

摘要

The present invention is a novel and improved method and apparatus for performing position location in wireless communications system. One embodiment comprises a method for performing position location i n a wireless communication system using a set of signals transmitted from a set of satellites including the steps of receiving signal samples, rotating an acquisition code by a first rotation amount yielding a rotated acquisition code, despreading said signal samples using rotated acquisition code yielding despread data, accumulating said despread data over a first duration yielding partially accumulated data , rotating said partially accumulated data by a second rotation amount yielding rotated data and accumulating said rotated data.
