    Performance Limits and Geometric Properties of Array Localization by Han, Yanjun, Zhang, Xiao-Ping, Meng, Huadong, Shen, Yuan, Win, Moe Z

    Published 2017
    “…In view of the Cramér-Rao bound, we first derive the localization information for static scenarios and demonstrate that such information is a weighed sum of Fisher information matrices from each anchor-antenna measurement pair. Each matrix can be further decomposed into two parts: 1) a distance part with intensity proportional to the squared baseband effective bandwidth of the transmitted signal and 2) a direction part with intensity associated with the normalized anchor-antenna visual angle. …”
