  • Detection And Prevention Of Errors In Transmission (AREA)

Abstract

FIELD: computer engineering and communications engineering. SUBSTANCE: method uses code construction that makes it possible both to actively control single errors and long error bursts using corrective abilities of internal Bose-Chaudhuri-Hocquenghem code (n,k) and external Reed-Solomon code (N, K) with character interleaving and to perform code synchronization using for numbering group of first code words of frame as sync pulses, numbers of adjacent classes of Bose-Chaudhuri-Hocquenghem code (n,k) corresponding to character combination kof transmitted Bose-Chaudhuri-Hocquenghem code (n,k+k). Character combination kof remaining code words of frame are used for transmitting individual and/or group address required for code separation of user groups and respective unique combination character position locators of external Reed-Solomon code used for encoding and decoding information addighed to definite group of users. EFFECT: provision for transmitting group or individual digital data of large capacity and high confidence over radio channel in spite of pulse interferences and Rayleigh fadings occurring in communication channels.

Изобретение относится к вычислительной технике и технике связи. Его использование в системах массового обслуживания позволяет передавать групповую и индивидуальную цифровую информацию больших объемов с высокой достоверностью по радиоканалу, несмотря на импульсные помехи и рэлеевские замирания, возникающие в канале связи. Этот результат достигается благодаря тому, что применяемая кодовая конструкция позволяет как активно бороться с одиночными ошибками и длинными пакетами ошибок, используя корректирующие способности внутреннего кода (n,k) Боуза-Чоудхури-Хоквингема (БЧХ) и внешнего кода (N,K) Рида-Соломона (PC) с перемежением символов, так и осуществлять кадровую синхронизацию, применяя для нумерации совокупности первых кодовых слов кадра, используемых в качестве синхропосылки, номера смежных классов кода (n,k) БЧХ, соответствующих комбинациям k1 символов передаваемого кода (n,k+k1) БЧХ. Комбинации k1 символов остальных кодовых слов кадра используется для передачи индивидуального и/или группового адреса, необходимого для кодового разделения групп абонентов и соответсвующего уникальному сочетанию локаторов позиций символов внешнего кода PC, применяемого для кодирования и декодирования информации, предназначенной определенной группе абонентов.The invention relates to computing and communication technology. Its use in queuing systems allows the transfer of large-volume group and individual digital information with high reliability over the air, despite impulse noise and Rayleigh fading occurring in the communication channel. This result is achieved due to the fact that the applied code construction allows one to actively deal with single errors and long error packets using the correcting abilities of the Bowes-Chowdhury-Hawkingham (BCH) internal code and Reed- (N, K) external code Solomon (PC) with alternating characters, and carry out frame synchronization, using for numbering the first set of code words of the frame used as a clock package, the numbers of adjacent code classes (n, k) of the frequency response corresponding to combinations of k 1 transmitted characters code (n, k + k 1 ) BCH. Combinations of k 1 characters of the remaining codewords of the frame are used to transmit an individual and / or group address required for code separation of subscriber groups and corresponding to a unique combination of character position locators of the external PC code used to encode and decode information intended for a specific subscriber group.
