摘要：
Location Determination in an indoor environment is a challenge that faces the wireless industry. The concept of indoor geolocation was established in order to provide the user's location inside buildings during an emergency where GNSS services are not effective. Keeping public safety in mind, it is not only important to estimate the position, but also to provide a high level of reliability. The paper presents practical results and issues related to the accuracy of an indoor geolocation system which uses a WCDMA signal at a 2.45 GHz carrier frequency. The experiment employs a hybrid TDOA/RSS algorithm and a TDOA only algorithm. Practical results indicate that the performance is improved by using hybrid TDOA/RSS algorithm as compared to TDOA alone.
