Estimation of probabilities of reception noiseproof code in channels with independent and grouped errors
In article formulas are resulted and calculation of probabilities of reception of a noiseproof code for the binomial channel and the channel with grouping of errors is described. Calculation of probabilities of the correct reception, not found out error and code deleting is described. The probability of not found out error for the channel with independent errors pays off under the exact formula taking into account a code spectrum. For the channel with grouping of errors more simple approached formula on volume of spheres, taking into account transformation factor is used. As the channel with grouping of errors are used the modified model of the channel on Purtov and markov channel model. Results of calculations of probabilities of reception for code BCH (31,16,7) and code Goley (23,12,7) with correction of 3 errors in channels with independent and grouped errors are resulted.
