On the Optimal Performance in Asymmetric Gaussian Wireless Sensor Networks With Fading
收藏 引用
IEEE TRANSACTIONS ON SIGNAL PROCESSING 2010年 第4期58卷 2436-2441页
作者: Behroozi, Hamid Alajaji, Fady Linder, Tamas Queens Univ Dept Math & Stat Kingston ON K7L 3N6 Canada
We study the estimation of a Gaussian source by a Gaussian wireless sensor network (WSN) where distributed sensors transmit noisy observations of the source through a fading Gaussian multiple access channel to a fusio... 详细信息
