Abstract: A method for tracking one or more portable devices in real time to detect theft of the one or more portable devices is provided. The method enables, firstly, interrogating a Radio Frequency Identification (RFID) tag via a RFID reader during successive sweep intervals. The sweep interval represents active state of the RFID reader. Secondly, the method enables receiving one or more pairing information from the RFID tag. Further, the method enables comparing the one or more pairing information with corresponding one or more pairing information stored in the RFID reader. Finally, the method enables generating an alert signal via the wearable-band or the one or more portable devices when the one or more pairing information does not match with the corresponding one or more pairing information stored in the RFID reader.

Abstract: Techniques for performing time tracking in a communication system utilizing a cyclic prefix are described. In an aspect, a receiver may detect for large timing errors based on early and late received samples obtained with early and late FFT windows, respectively. The receiver may derive first and second channel impulse response (CIR) estimates based on the early and late received samples, respectively, determine an early channel energy based on the first CIR estimate, determine a late channel energy based on the second CIR estimate, compute an update amount based on the early and late channel energies, and update the FFT window position based on the update amount. In another aspect, the receiver may perform time tracking with an inner time tracking loop (TTL) and an outer TTL. The receiver may update the FFT window position in coarse steps with the outer TTL and in fine steps with the inner TTL.
