Adaptive Coding for Transmission of Position Information Over the Limited-band Communication Channel1

The problem is considered of transmission object position estimates using band limited communication channels. Due to advances in technology, it is feasible to have a tracking filter attached to the sensor, and transmit only the condensed information as a tradeoff between computation and communication requirements. This paper proposes a scheme, which minimizes transmission data rate by sending adaptively encrypted innovations. It is assumed that the second derivative of the object position is bounded above by the known constant, and the sample rate is the design parameter. Adaptive tuning procedure for the coder range parameter is proposed and numerically studied.
