EECI09: Estimation over networks
| Prev: Cooperative control | Course home | Next: Distributed protocols and verification |
In this lecture we consider some results when a process is being observed by multiple sensors, or when the sensor is transmitting information across a network consisting of multiple communication channels combined in an arbitrary topology. We consider both the analog erasure and digital noiseless channel models. For the digital noiseless channel model, we provide stability conditions. For the analog erasure channel model, we solve the two block design problem for optimal performance.
