Abstract

SE SUMINISTRA UN TRANSMISOR (10) CON UN CODIFICADOR TOMLINSON PARA LA CONSERVACION DE LA DISTRIBUCION (25) QUE DISTORSIONA LAS SEÑALES DE DATOS CONFORMADAS (20) DE MANERA QUE POTENCIA DE CADA SEÑAL DE DATOS QUE SALE DEL CODIFICADOR SEA SUBSTANCIALMENTE SIMILAR A LA POTENCIA DE LA SEÑAL DE DATOS QUE PENETRA EN EL CODIFICADOR Y DE MANERA QUE EN LA TRANSMISION DE LA SEÑAL DE DATOS PREDISTORSIONADA SOBRE EL CANAL (40), EL EFECTO DE ISI DEL CANAL SE ELIMINA SUBSTANCIALMENTE. EL TRANSMISOR ESTA PRIMARIAMENTE DISEÑADO PARA SISTEMAS DE MODULACION CODIFICADA QUE UTILIZAN UN CODIGO "COSET", Y LA PREDISTORSION SE REALIZA PREFERIBLEMENTE DE ACUERDO CON UNA FUNCION LINEAL (1), EN LA QUE RK ES UNA SEÑAL DE DATOS QUE PENETRA EN EL CODIFICADOR, A1 Y B1 SON LOS COEFICIENTES DE LOS POLINOMIOS RELATIVOS A LA RESPUESTA DE IMPULSO DEL CANAL, XK ES LA SEÑAL DE DATOS PREDISTORSIONADA QUE SALE DEL CODIFICADOR, Y SK SE ELIGE PARA PROVOCAR QUE LA POTENCIA DE LA SEÑAL DE XK SEA APROXIMADAMENTE IGUAL A LA POTENCIA DELA SEÑAL RK. SE PRESENTAN DIFERENTES METODOS PARA ESCOGER SK. TAMBIEN SE SUMINISTRAN RECEPTORES (50) QUE COOPERAN CON LOS TRANSMISORES PRESENTADOS (10).
