In classical case there is simplest method of error correction with using three equal bits instead of one. In the paper is shown, how the scheme fails for quantum error correction with complex vector spaces of usual quantum mechanics, but works in real and quaternionic cases. It is discussed also, how to implement the three qubits scheme with using encoding of quaternionic qubit by Majorana spi...
This paper uses the semiparametric error correction model (Li andWooldridge, 2002) and investigates the dynamics of wage, employment and labor efficiency after introducing five-day work week to the Korean labor market. Efficient working hour function is obtained by nonparametric method (polynomial approximation) and the dynamics are investigated using impulse response analysis. Average derivati...
In this paper we utilize both the implicit residual source correlation and the explicit redundancy from a forward-error-correction (FEC) scheme for the error protection of packetized variable-length encoded source indices. The implicit source correlation is exploited in a novel symbol-based soft-input a-posteriori probability (APP) decoder, which leads to an optimal decoding process in combinat...
The entanglement-assisted stabilizer formalism provides a useful framework for constructing quantum error-correcting codes (QECC), which can transform arbitrary classical linear codes into entanglement-assisted quantum error correcting codes (EAQECCs) by using pre-shared entanglement between the sender and the receiver. In this paper, we construct five classes of entanglement-assisted quantum M...
The [[7,1,3]] quantum error correction code uses sets of three syndrome measurements to separately detect bit-flip and phase-flip errors. To comply with the strictures of fault tolerance and thus stem the possible spread of errors to multiple qubits, each set of syndromes is repeated twice. Still, there remains flexibility in the order in which the sets of syndromes are implemented. Here we exp...
We give a short introduction to operator quantum error correction. This is a new protocol for error correction in quantum computing that has brought the fundamental methods under a single umbrella, and has opened up new possibilities for protecting quantum information against undesirable noise. We describe the various conditions that characterize correction in this scheme.
The large-scale seismic acquisition system (LSAS) is a kind of field data acquisition system in super scale. It can cover hundreds of square kilometers. To implement the real time transmission of so much data, speed and reliability are the most important criteria of the system. Based on 8b10b code, this paper discusses frame sync technology, error correction code (ECC), and a co-design method o...
This paper 1 investigates the efficiency of the applied redundancy via channel coding or source coding diversity in narrowband short range wireless networks on the example of Bluetooth. The efficiency of such approaches is investigated in order to be applied as data reliability improvement techniques. Taking into account their error correction capabilities, the packet error probabilities are es...
Money demand in Venezuela is modeled using structural time series and error correction approaches, for the period 1993.1 to 2001.4. The preferred model features seasonal cointegration and was estimated following a structural time series approach. There are similarities in the long-run behavior of money demand associated with the structural time series and error correction approaches. Estimated ...
