Design of convolutional tornado code

Dual-Objective-Based Tornado Design Philosophy

Tornadoes represent a unique natural hazard because of the very low probability of occurrence, short warning times (on the order of only a fewminutes), and the intense and destructive forces imposed on engineered and nonengineered buildings. The very low-probability/very high-consequence nature of a tornado strike makes designing for survival and reducing damage under typical financial constrai...

BLIND PARAMETER ESTIMATION OF A RATE k/n CONVOLUTIONAL CODE IN NOISELESS CASE

This paper concerns to blind identification of a convolutional code with desired rate in a noiseless transmission scenario. To the best of our knowledge, blind estimation of convolutional code based on only the received bitstream doesn’t lead to a unique solution. Hence, without loss of generality, we will assume that the transmitter employs a non-catastrophic encoder. Moreover, we consider a c...

Description of a quantum convolutional code.

We describe a quantum error correction scheme aimed at protecting a flow of quantum information over long distance communication. It is largely inspired by the theory of classical convolutional codes which are used in similar circumstances in classical communication. The particular example shown here uses the stabilizer formalism. We provide an explicit encoding circuit and its associated error...

Threshold Saturation for LDPC Convolutional Code Ensembles

Low-density parity-check (LDPC) codes, originally invented by Gallager in 1963, are now well-known for their good performances. Their convolutional counterpart was introduced by Felström and Zigangirov in 1999 and have already been shown to be able to achieve the Shannon capacity under low-complexity iterative decoding algorithms. In principle, the belief-propagation (BP) threshold of the convo...
