Position location error analysis by AOA and TDOA using a common channel model for CDMA cellular environments

AOA and TDOA are known to be promising methods and are developed separately. Combination or cooperation of the two methods has not been possible due to lack of the applicable channel models. The COST-207 model is utilized to provide the angular information for the AOA method. The angular characteristic of the channel can be obtained from the given temporal channel model, hence fusing of the approaches is now possible. Different properties of the methods are revealed to verify the proposition in literature. As a future research area, the fusing of the two different methods for better reliability and accuracy is mentioned
