This paper addresses issues on control and coding co-design in the context of low-energy sensors. We particularly focus on issues of low energy consumption (energy-aware). To this aim, we propose to use a coding strategy with the ability to quantify and to differentiate stand-still signal events from changes in the source (level crossing detector). The standstill signal event is then modulated with a low energy carrier, whereas the changes of levels will be modulated with enough energy. Coding is then effectuated by defining a 3-valued alphabet. The paper studies the closed-loop properties of such arrangement. In particular, we derive conditions required so that this coding algorithm preserves closed loop stability.
