Abstract
LA INVENCION TRATA DE UN RECEPTOR (5A, 5B, 10) CON DOS RAMALES DE RECEPCION (A, B) POR LO MENOS, CON UN DISPOSITIVO (10) PARA LA COMBINACION DE LOS RAMALES DE RECEPCION (A, B). SE DEBE EVITAR QUE SEA NECESARIO UN CORRECTOR SEPARADO PARA CADA RAMAL DE RECEPCION. SE PROPONE QUE CADA RAMAL DE RECEPCION (A, B) PRESENTE, RESPECTIVAMENTE, UN FILTRO AJUSTADO (1A, 1B) Y, RESPECTIVAMENTE, UN DISPOSITIVO (6A, 6B) PARA LA CONSTITUCION DE LA FUNCION DE AUTOCORRELACION RESPECTIVA (A1, A2) PARA LA RESPUESTA DE IMPULSO ESTIMADA (H1, H2) DE CADA RAMAL DE RECEPCION Y QUE EL RECEPTOR (5A, 5B, 10) PRESENTE UN PRIMER DISPOSITIVO DE ADICION (11) PARA LA ADICION DE SEÑALES DE SALIDA (Z SUB A'', Z SUB B'') EQUILIBRADAS CON LOS FACTORES DE PONDERACION DE LOS FILTROS AJUSTADOS (1A, 1B) PARA UNA PRIMERA SUMA (S1) Y UN SEGUNDO DISPOSITIVO DE ADICION (12) PARA LA SUMA DE LAS FUNCIONES DE AUTOCORRELACION (A1, A2), EQUILIBRADOS CON LOS FACTORES DE PONDERACION DE LOS RAMALES DE RECEPCION PARA UNA SEGUNDA SUMA, Y UN CORREPTOR QUE VALORE LA PRIMERA (S1) Y LA SEGUNDA SUMA (S2), DONDE LOS FACTORES DE PONDERACION SON MAS O MENOS CONTRARIAMENTE PROPORCIONALES A UNA POTENCIA DE PERTURBACIONES (O12, O22) MOMENTANEA EN LOS RESPECTIVOS RAMALES DE RECEPCION (A,B). SISTEMAS DIGITALES DE TRANSMISION.
