Abstract
La presente invencion se refiere a un procesador de datos que revela una señal de datos que tiene una pluralidad de símbolos en niveles multiples. El procesador de datos, en respuesta a cada uno de los símbolos, determina la métrica de trayectoria más baja que caracteriza la señal de datos, y elige uno de una pluralidad de conjuntos de valores de secciones en respuesta a la métrica de trayectoria más baja. Un seleccionador (82, 82') responde al conjunto selecto de valores de secciones al seccionar los símbolos de niveles multiples. Puede haber solo dos conjuntos de valores de secciones de pluralidad de conjuntos de valores de secciones, en donde cada uno de solo dos conjuntos tiene tres niveles de secciones. En forma alterna, puede haber solo cinco conjuntos de valores de secciones en la pluralidad de conjuntos de valores de secciones, en donde cada uno de los solo cinco conjuntos tienen cinco niveles de secciones. Como una alternativa aun adicional, puede haber solo dos conjuntos de valores de secciones en la pluralidad de conjuntos de valores de secciones, en donde cada uno de solo dos conjuntos tiene un mínimo de seis niveles de secciones.
