英文摘要： Ubiquitous localization technologies are to provide accurate information of anyone's position in anytime and anywhere. Therefore, the accuracy of the wireless localization and the seamless navigation become very critical for the heterogeneous network of ubiquitous environment. This research project will focus on studying the key technologies for the future wireless localization systems, which include signal processing, data fusion and artificial intelligence, and presenting the localization scheme utilizing the ubiquitous wireless signals. The main research contents include the following four themes: 1) Improving the performance of wireless localization technologies of the localization scheme for the next generation cellular communication systems using interference cancellation and beamforming; 2) Optimizing the time synchronization and the cooperative localization technology, and improving the localization technology of the localization scheme with low-earth-orbit satellite signals; 3) Improving the performance of the traditional indoor wireless localization, and designing localization relay technologies for tunnel wireless channels; 4) Realizing the seamless wireless localization through improved data-fusion algorithms; 5) Proposing brand new research topics related to adaptive wireless localization systems. Through the above research targets, we expect to design a fast, precise and robust wireless localization technology for ubiquitous environments.
