Abstract

A PARTIR DE LA SECUENCIA DE BITS DE INFORMACION A TRANSMITIR, EL CODIFICADOR FORMA UNA SECUNDA SECUENCIA (T2) DE BITS C{SUB,N}, QUE INCLUYE UN SUBCONJUNTO REDUNDANTE. UNA CODIFICACION DIFERENCIAL DE LA FORMA D{SUB,N} = C{SUB,N}+{SUB,F}({SUB,N}) CON F({SUB,N}) < N PRODUCE UNA TERCERA SECUENCIA (T3) DE BITS D{SUB,N}. LA SEÑAL EMITIDA REPRESENTA LOS BITS DE LA TERCERA SECUENCIA (T3) EN UN ORDEN DETERMINADO. HABIENDOSE OBTENIDOS DATOS DE PROBABILIDAD R{SUB,N} ASOCIADOS A LOS BITS D{SUB,N}, EL RECEPTOR CALCULA ESTIMACIONES DE LOS BITS C{SUB,N} DEL SUBCONJUNTO REDUNDANTES EN FUNCION DE SIGNO DE R{SUB,N}R{SUB,F}({SUB,N}). EXPLOTANDO LA REDUNDANCIA, EL RECEPTOR PUEDE DETECTAR LOS BITS C{SUB,N} DE DICHO SUBCONJUNTO QUE TIENEN ESTIMACIONES ERRONEAS, Y RECTIFICAR EL SIGNO DEL MENOS FIABLE DE LOS DOS DATOS DE PROBABILIDAD R{SUB,N} Y R{SUB,F}({SUB,N}) ASOCIADOS. LOS OTROS BIT C{SUB,N} DE LA SEGUNDA SECUENCIA (T2) SE BENEFICIAN ENTONCES DE UNA PROTECCION SUPLEMENTARIA SI HAY AL MENOS UN BIT C{SUB,N} DELSUBCONJUNTO REDUNDANTE TAL QUE N''= F({SUB,N}) 0 F({SUB,N''}) = N O F({SUB,N}).
