Abstract

SE PRESENTA UN METODO PARA PROTEGER BITS DE INFORMACION EN EL QUE LOS BITS DE LOS DATOS DE ENTRADA, AL MENOS ALGUNO DE LOS CUALES HAN DE PROTEGERSE, SE CLASIFICAN EN BASE A UNA INFORMACION DETERMINADA DE UN SUBCONJUNTO DE BITS DE LOS DATOS DE ENTRADA. SE APLICA UNA TECNICA DE CODIFICACION DE CONTROL DE ERRORES PARA AL MENOS PARTE DE LOS BITS CLASIFICADOS. EN UNA CONCENTRACION MAS ADECUADA, LA CORRIENTE DE DATOS DE ENTRADA DE LOS BITS DE UN CODIFICADOR DE VOZ SE SEPARA EN MATRICES DE BITS. UNA PRIMERA MATRIZ (302) COMPRENDE LOS BITS CODIFICADORES DE LA VOZ QUE NECESITAN PROTECCION DE ERRORES, CON LOS BITS DISPUESTOS EN ORDEN DE IMPORTANCIA DETERMINADO POR EL MODO DE LA VOCALIZACION. LA SEGUNDA MATRIZ (303) COMPRENDE LOS BITS QUE NO ESTARAN PROTEGIDOS CONTRA ERRORES. LOS BITS DE LA PRIMERA MATRIZ SE DISPONEN EN LA ENTRADA DE UN DECODIFICADOR (304), DESPUES LOS BITS CODIFICADOS SE COMBINAN (305) CON LOS BITS DE LA SEGUNDA MATRIZ (303) PARA FORMAR UNA CORRIENTE DE BITS.
