Abstract

SISTEMA DE GENERACION DE CODIGOS ORTOGONALES,DONDE UN PRIMER GENERADOR (1) DE CODIGO GENERA UNA SECUENCIA DE CODIGOS DE LA LECTURA DE UN CONTADOR (2) CUYA SECUENCIA ES DIFERENTE DEL CODIGO GENERADO POR UN SEGUNDO GENERADOR DE CODIGO (1'') DIRIGIDO POR EL MISMO CONTADOR. CADA GENERADOR DE CODIGO COMPRENDE UN NUMERO DE ADAPTADORES INDIVIDUALES Y UN CONTADOR DIRECTOR DE GENERADORES (3.I) DE SUBCODIGO, LOS SUBCODIGOS GENERADOS(GI) JUNTOS FORMAN EL CODIGO, DONDE AL MENOS UN GENERADOR DE SUBCODIGO(3.I) DEL PRIMER GENERADOR (1) DE CODIGO GENERA UN SUBCODIGO (GI) EL CUAL ES DIFERENTE DEL SUBCODIGO GI'' DEL GENERADOR DE SUBCODIGO (3.I'') SIMILAR DEL SEGUNDO GENERADOR DE CODIGO (1'')
