Abstract

UN SISTEMA DE COMUNICACIONES DE ACCESO MULTIPLE DE DIVISION DE CODIGOS (CDMA), QUE CONTIENE UN CANAL DE LLAMADAS QUE SE USA PARA INFORMAR A MOVILES SILENCIOSOS QUE ESTAN SIENDO LLAMADOS. EN EL SISTEMA, EL CANAL DE LLAMADAS SE ELIGE PARA QUE SEA LA SEÑAL MAS FUERTE DE SUPERPOSICION, DE FORMA QUE ALCANCE A MOVILES QUE ESTEN SITUADOS SOBRE LIMITES EXTREMOS CELULARES. LAS OTRAS SEÑALES DE INTERFERENCIA QUE SE SIENTEN PORQUE SE SUPERPONEN CON EL CANAL DE LLAMADA PUEDEN EVITARSE TENIENDO LOS MOVILES QUE PRIMERO DEMODULAN LA SEÑAL DEL CANAL DE LLAMADA Y DESPUES LA SUBSTRAEN ANTES DE LA DEMODULACION DE SU PROPIA SEÑAL.
