Title: Method of messages acceptance and transmission within communication system
Inventor: KVASHENNIKOV VLADISLAV VALENTINOVICH
IPC: H04L5/14
Filed: 2008-02-26
Granted: 2009-09-27
Abstract: FIELD: communication means. 
     SUBSTANCE: method of transmission and receiption of messages within communication system pertains to communication technique and may be employed for reliable and noise-immune transmission of messages protected with noise-immune code. Technical result is achieved due to the fact, that on the transmitting site outlet sequence presenting bit-by-bit modulo n sum, two noise-immune codes and synchronising sequences are recurrently continued. On receiving site syndrome for the received sequence is calculated, synchronising sequence is detected and cycle synchronisation of the noise-immune code is set. There after bit-by-bit modulo n sum two accepted and synchronising sequences, noise-immune code and its recurrent continuation are separated. There after syndrome and its recurrent continuation preceding sliding window and following it for the rest of code symbols is calculated. When the number of zero syndrome components for the rest of the code symbols and its recurrent continuation exceeding threshold value, information is restored and given to the recipient. If threshold value is not exceeded, sliding window is off set by one symbol and computations are repeated from the beginning. 
     EFFECT: improved noise-immunity of messages transmitted in the communication system.
