摘要：An emerging requirement for processing GNSS signals indoor, where signals are very weak and subject to spatial fading, has typically led receiver designers to use of longer coherent integration intervals that provide the additional processing gain required for the detection and processing of such weak signals. However, the physical motion of the handset imposed by the user limits the effectiveness of longer coherent integration intervals due to the spatial decorrelation of the multipath-faded GNSS signal. Research at the University of Calgary suggests factors that receiver designers might consider to address this problem.
