This paper addresses the state feedback stabilization problem for linear timeinvariant systems, where the sensors and the controller are geographically separated and connected over a digital communication network. In particular, the case with the channel propagation delays is considered. A quantizer-controller pair is constructed to stabilize the unstable plant in the mean square sense. The sufficient condition on the data rate of the channel for stabilization is derived. An illustrative example is given to demonstrate the effectiveness of the proposed method.
