In this paper, the authors deal with the problem of stabilizing an unstable system through networked control over the wireless medium. In such a situation, a remote sensor communicates the measurements to the system controller through a noisy channel. In particular, in the AWGN scenario, they show that protograph-based LDPC convolutional codes achieve anytime reliability and they also derive a lower bound to the signal-to-noise ratio required to stabilize the system. Moreover, on the Rayleigh-fading channel, they show by simulations that resorting to multiple sensors allows achieving a diversity gain.
