  This paper is concerned with the problem of stabilizing continuous-time
linear time-invariant systems subject to quantization and Denial-of-Service
(DoS) attacks. In this context, two DoS-induced challenges emerge with the
design of resilient encoding schemes, namely, the coupling between encoding
strategies of different signals, and the synchronization between the encoder
and decoder. To address these challenges, a novel structure that is equipped
with a deadbeat controller as well as a delicate transmission protocol for the
input and output channels, co-designed leveraging the controllability index, is
put forward. When both input and output channels are subject to DoS attacks and
quantization, the proposed structure is shown able to decouple the encoding
schemes for input, output, and estimated output signals. This property is
further corroborated by designing encoding schemes as well as conditions that
ensure exponential stability of the closed-loop system. On the other hand, when
only the output channel is subject to network phenomenon, the proposed
structure can achieve exponential stabilization without acknowledgment (ACK)
signals, in contrast to existing ACK-based results. Finally, a numerical
example is given to demonstrate the practical merits of the proposed approach
as well as the theory.
