Chaos-Based Anytime Reliable Coded Communications
Anytime reliable communication systems are needed in contexts where the
property of vanishing error probability with time is critical. This is the case
of unstable real time systems that are to be controlled through the
transmission and processing of remotely sensed data. The most successful
anytime reliable transmission systems developed so far are based on channel
codes and channel coding theory. In this work, another focus is proposed,
placing the stress on the waveform level rather than just on the coding level.
This alleviates the coding and decoding complexity problems faced by other
proposals. To this purpose, chaos theory is successfully exploited in order to
design two different anytime reliable alternatives. The anytime reliability
property is formally demonstrated in each case for the AWGN channel, under
given conditions. The simulation results shown validate the theoretical
developments, and demonstrate that these systems can achieve anytime
reliability with affordable resource expenditure.Comment: 31 pages, 7 figure
