Location Estimation In Wireless Communication Systems, Kejun Tong
Electronic Thesis and Dissertation Repository
Localization has become a key enabling technology in many emerging wireless applications and services. One of the most challenging problems in wireless localization technologies is that the performance is easily affected by the signal propagation environment. When the direct path between transmitter and receiver is obstructed, the signal measurement error for the localization process will increase significantly. Considering this problem, we first propose a novel algorithm which can automatically detect and remove the obstruction and improve the localization performance in complex environment. Besides the environmental dependency, the accuracy of target location estimation is highly sensitive to the positions of reference …

Continuous heart rate monitors (CHRM) can give unique insights into a person's physiological and psychological state; however, existing CHRMs are not suitable for continuous monitoring because they do not provide beat-to-beat accuracy and comfort needed for all-day use. Our group is currently developing a miniature earlobe mounted CHRM system which is both comfortable and provides beat-to-beat accuracy, based on a miniature heart rate sensing technology developed previously in our lab. The objective of this thesis is to design low power system firmware to perform key tasks: i) acquire heart rate and skin temperature data from wearable sensors; ii) signal process …
