CRC Error Probability under Batch Random Noise
Automatic Control and Computer Sciences. 2018. Vol. 52. No. 8. P. 1049-1058.
Baranov A., Baranov P.
We consider error probabilities in protocols using CRC to detect distortions in transmitted batches. A probability-theory model of an additive long-term noise is constructed as a sequence of independent noise blocks of a prescribed length. We show that there are conditions to be imposed on the form of the k-order polynomial forming the CRC and on block size s such that the error probability α is close to 2−k and does not depend on s provided that distortion probability P1 is high.

Some probability-theoretical models of packet-mode-transmitted information distortions have been considered. The main attention has been paid to distortions, including the possible interferences that affect several transmission cycles. Distortions are simulated by a sequence of impacts determined by dependent random variables. Correspondingly, k-dimensional CRC values also allow them to be represented as the sum of k-dimensional, differently distributed, ...

The paper considers certain probability-theoretic models of packet mode-transferred information distortions. Attention is drawn mainly to distortions, including possible interferences influencing multiple transfer cycles. Distortions are modeled by a consequential impacts that are defined by dependent random variables. K-dimensioned values of CRC, respectively allow representation as a sum of k-dimensioned independent random variables.

The article analyzes possibilities of errors in telecommunication protocols using packet data transmission. Probabilistic model of a prolonged-action additive interference is represented as a sequence of executions of independent interference blocks with definite length. The paper shows that in certain conditions concerning a polynomial of degree k, used for creation of CRC code, with block ...

The paper examines probability-theoretic models of information distortion at message level. We research control sum distribution segments that are typical for network protocols like TCP.
As an addition operation we use both bitwise coordinate addition and addition of numbers in binary code with carry. Control sum error probability for asymptotic assessments provided distortion probability is low ...

We present a method for synthesis of optimal control with feedback of nonlinear systems with separated linear part via quadratic criteria. This method is based on a specialmethod of successive approximations, which allows, under standard assumptions, to find optimal control within any finite time interval and to get the procedure of its construction. An example ...

We consider a stochastic model of changes of prices in real estate markets. We suppose that in a book of prices the changes happen in points of jumps of a Poisson process with a random intensity, i.e. moments of changes sequently follow to a random process of the Cox process type. We calculate cumulative mathematical ...
