THE STUDY OF THE IMPLEMENTATIONS OF THE ALGORITHM METHOD CHECKS SUMMATION (CRC) OF THE TRANSMITTED DATA

Error detection methods are designed to detect distortions in messages when they are transmitted through noisy channels. The main idea embodied in them is the transfer of redundant service information, which can be judged with some degree of probability about the reliability of the received data. The article discusses the use of the control summation method (Cyclic redundancy code, CRC) for data. For the CRC generation method in question, an application was written in a high-level Java language, which allows obtaining results and collecting statistics on the detection / non-detection of data transfer errors. The collected statistics show the probability of not detecting an error for the transmitted data block. To assess the likelihood of undetected distorted bits, the process of transferring data with erroneous bits was simulated. JavaDevelopmentKit software version 1.8 and the NetBeans IDE 8.0.2 development environment ar.
