Encoding and decoding schemes at an encoding device/transmitter and decoder device/receiver, respectively, for use in communicating the state of a system. In an example method carried out by an encoding device, state information x(k), which represents the current state of a monitored system, is measured. The encoding device calculates a state update parameter, based on: a message power constraint P; the covariance N of measurement noise associated with the channel over which encoded state information is to be transmitted; and the norm of the signal vector [s(k), x(k)], where s(k) is a stored state information parameter. The encoding device then calculates a message signal z(k) = G(k)*(x(k) –s(k)), which may then be transmitted to a remote decoder device, and calculates an updated version of the stored information s(k+1) = A*(s(k) + F(k)*z(k)). The encoding device replaces the stored state information s(k) with s(k+1). |
