Abstract

EL GRUPO DE POSIBLES SEÑALES DE EXCITACION SE SUBDIVIDE EN UNA MULTITUD DE SUBGRUPOS, EL PRIMERO DE LAS CUALES PROPORCIONA LA CONTRIBUCION PARA LA SEÑAL CODIFICADA NECESARIA PARA ESTABLECER UNA TRANSMISION A UNA VELOCIDAD MEDIA GARANTIZADA MEDIANTE LA RED, MIENTRAS LOS DEMAS SUMINISTRAN UNA CONTRIBUCION QUE, CUANDO SE AÑADE AL PRIMERO, PRODUCE UN AUMENTO DE VELOCIDAD MEDIANTE PASOS SUCESIVOS. EN EL LADO RECEPTOR SE GENERA UNA SEÑAL DECODIFICADA USANDO LA CONTRIBUCION DE EXCITACION DEL PRIMER SUBGRUPO SOLO SI LAS SEÑALES CODIFICADAS SE RECIBEN A LA VELOCIDAD MINIMA, MIENTRAS QUE PARA VELOCIDADES SUPERIORES A LAS DE LA VELOCIDAD MINIMA SE USAN TAMBIEN LAS CONTRIBUCIONES DE LOS SUBGRUPOS QUE HAN PERMITIDO DICHOS AUMENTOS DE VELOCIDAD.
