Abstract

DONDE LOS SISTEMAS ESTAN CONSTITUIDOS POR: a) UNA O VARIAS ESTACIONES BASE CELULAR UMTS QUE DAN SERVICIOS DE COMUNICACIONES CELULARES UMTS A LOS TERMINALES CERCANOS DENTRO DE SU AREA DE COBERTURA Y SE CONECTA VIA CABLE A (b); b) UNO O VARIOS REPETIDORES CERCANOS COMUNICADOS CON (c) EN OTRA DE LAS BANDAS UMTS, VIA RADIO; c) UNO O VARIOS REPETIDORES REMOTOS COMUNICADOS CON (b) EN UNA DE LAS BANDAS UMTS, Y CON (d) EN OTRA DE LAS BANDAS UMTS; Y, d) TERMINALES REMOTOS CELULARES UMTS COMUNICADOS CON (a) A TRAVES DE (b) Y (c). SE UTILIZA UN MECANISMO DE RECHAZO DE TERMINALES INTERFERENTES BASADO EN LA DISTORSION DE FASE DE LA SENAL TRANSMITIDA ENTRE (b) Y (c) PARA EVITAR LA INTRUSION DE (d) EN DICHA COMUNICACION ENTRE REPETIDORES; UN MECANISMO DE ECUALIZACION CON LOS RECEPTORES DE (b) Y (c) PARA LA COMUNICACION ENTRE ELLOS, COMPENSATORIO DE LOS EFECTOS DE DISTORSION; UN MECANISMO DE LIMITACION DE GANANCIA DE SENAL RADIADA Y RECIBIDA DE (b) Y (c); Y UN MECANISMO DE CORTE DE TRANSMISION DE SENAL RADIO EN (b) Y (c) CUANDO LA SENAL CORRESPONDIENTE DE ENTRADA SE ENCUENTRA POR DEBAJO DE UN UMBRAL AJUSTABLE POR EL OPERADOR
