Abstract
Characterization and enhancement of a mobile local scattering environment. The system includes a channel component and a link control component, wherein the channel component facilitates communication of a ping signal, which is used to estimate the delay spread characteristics and/or angle of arrival in order to characterize the mobile local scattering environment. This information is sent to the link control component, which enhances radio link performance based on the received information. The system can be used to assist in E-911 location applications, such as determining the location of an indoor user.
