Abstract :
A major concern in using GPS is satellite visibility, especially in urban canyons and indoor applications. We demonstrate techniques to use the communication link to enhance the sensitivity of GPS receivers in wireless applications. We analyze the performance of the different sensitivity enhancement schemes. Receiver operating characteristics (ROC) and improvements in sensitivity are presented and discussed.
