the rank-k numerical range has a close connection to the construction of quantum error correction code for a noisy quantum channel. for noisy quantum channel, a quantum error correcting code of dimension k exists if and only if the associated joint rank-k numerical range is non-empty. in this paper the notion of joint rank-k numerical range is generalized and some statements of [2011, generaliz...

In this paper, we propose an error correction method using text corpora. In this method, recognition errors are corrected using phonetically similar examples in the text corpora. The reliability of the correction hypotheses are judged according to their semantic consistency and their phonetic similarity to the original input. We previously proposed an error correction method that uses a treeban...

We introduce a method that allows analytical or semianalytical estimating of the post-error correction bit error rate (BER) when a forward-error correction is utilized for transmitting information through a noisy channel. The generic method that applies to a variety of error-correction schemes in the regimes where the BER is low is illustrated using the example of a finite-size code approximate...

This paper presents an error correction method known as restorative feedback (RFB) that provides error-correction for both permanent and temporal logic faults in any M-ary logic system. The RFB method is a variant of triple modular redundancy (TMR), which achieves error correction in logic circuits by using three-fold redundancy. Unlike TMR, the RFB method has well-defined application to arbitr...

The degree to which measurement accuracy in a vector network analyzer can be improved through error correction is dependent on a number of factors. Modern error correction methods have improved the system accuracy and simplified the calibration procedure. Methods are in place to determine the accuracy of error corrected measurements. And the quality of the calibration standards is key to system...

Additive iterative method in combination with averaging of dithered samples is designed for self-correction of ADC linearity error in the paper. Iterative method is one of the automated error correction techniques. Dithering is a special tool for quantizer performance enhancement. Dither theory for Gaussian noise and averaging has been used for exhibition of method abilities in ADC characterist...

We present a probabilistic error correction technique to be used with an average magnitude di erence function (AMDF) based pitch detector. This error correction routine provides a very simple method to correct errors in pitch period estimation. Used in conjunction with the computationally e cient AMDF, the result is a fast and accurate pitch detector. In performance tests on the CSTR (Center fo...

we present an approach to design of fault tolerant computing systems. in this paper, a technique is employed that enable the combination of several codes, in order to obtain flexibility in the design of error correcting codes. code combining techniques are very effective, which one of these codes are turbo codes. the algorithm-based fault tolerance techniques that to detect errors rely on the c...
