Abstract: A method and system for determining a position of a mobile device in an indoor environment by an access point is provided. The method includes obtaining identity information of the mobile device. The method includes extracting signal characteristics of the mobile device corresponding to the identity information. Further, the method includes determining the position of the mobile device based on the signal characteristics of the mobile device. The position of the mobile device is determined based on the signal characteristics of the mobile device received from a plurality of access points along with the information of the plurality of access points such as location information and identity information of the access points. The determined position is sent to the mobile device. The access point implements robust multipath mitigation algorithms while determining the position of the mobile device as there is no battery power limitation at the access point.

Abstract: A method for acquisition of a weak signal from a satellite in the presence of a strong interfering signal from another satellite is disclosed. The method encompasses identifying the auto-correlation peak due to the weak satellite signal from the cross correlation peaks due to the strong satellite signal. This invention presents a method and apparatus of acquiring a weak satellite signal in the presence of a strong interfering satellite signal in a receiver by two techniques, namely, the millisecond boundary correlation histogram method, and the frequency response correlation histogram method. Both the techniques distinguish between the correlation characteristics for auto-correlation and cross-correlation. The apparatus presented in the invention implements the methods of weak satellite signal acquisition in presence of a strong interfering satellite signal in a pseudorandom noise (PRN) receiver.
