Abstract

UN SISTEMA DE COMUNICACION DE ESPECTRO EXTENDIDO, DE ACCESO MULTIPLE PROCESA UNA SERIE DE DE SEÑALES DE INFORMACION RECIBIDAS POR UNA ESTACION DE PORTADORA DE RADIO (RCS) SOBRE LINEAS DE TELECOMUNICACION PARA LA TRANSMISION SIMULTANEA SOBRE UN CANAL DE RADIOFRECUENCIA (RF) COMO UNA SEÑAL MULTIPLEXADA POR DIVISION DE CODIGO (CDM) A UN GRUPO DE UNIDADES DE ABONADO (SUS). LA RCS RECIBE UNA SEÑAL DE PETICION DE LLAMADA QUE SE CORRESPONDE CON UNA SEÑAL DE INFORMACION DE LINEA DE TELECOMUNICACION, Y UNA SEÑAL DE IDENTIFICACION DE USUARIO QUE DEFINE UN USUARIO QUE RECIBIRA LA LLAMADAS. LA RCS INCLUYE UNA SERIE DE DE MODEMS DE ACCESO MULTIPLE POR DIVISION DE CODIGO (CDMA), UNO DE LOS CUALES SUMINISTRA UNA SEÑAL DE CODIGO DE MANDO GLOBAL. LOS MODEMS SUMINISTRAN SEÑALES DE CODIGO DE MENSAJE SINCRONIZADAS CON LA SEÑAL DE MANDO GLOBAL. CADA MODEM COMBINA UNA SEÑAL DE INFORMACION CON UNA SEÑAL DE CODIGO DE MENSAJE PARA SUMINISTRAR UNA SEÑAL CDM PROCESADA. LA RCS INCLUYE UN CONTROLADOR DE CANAL DEL SISTEMA QUE ESTA ACOPLADO PARA RECIBIR UNA LLAMADA REMOTA. SE CONECTA UN TRANSMISOR DE RF A TODOS LOS MODEMS PARA COMBINAR LAS SEÑALES CDMA PROCESADAS CON LA SEÑAL DE CODIGO DE MANDO GLOBAL PARA GENERAR UNA SEÑAL CDM. EL TRANSMISOR DE RF TAMBIEN MODULA UNA SEÑAL DE PORTADORA CON LA SEÑAL CDM Y TRANSMITE LA SEÑAL DE PORTADORA MODULADA A TRAVES DEL CANAL DE COMUNICACION DE RF A LAS SUS. CADA SU INCLUYE UN MODEM CDMA QUE ESTA TAMBIEN SINCRONIZADO CON LA SEÑAL DE MANDO GLOBAL. EL MODEM CDMA DESEXTIENDE LA SEÑAL CDMA Y SUMINISTRA UNA SEÑAL DE INFORMACION DESEXTENDIDA AL USUARIO. EL SISTEMA INCLUYE UN SISTEMA DE CONTROL DE ENERGIA DE CIRCUITO CERRADO PARA MANTENER UN NIVEL MINIMO DE ENERGIA DE TRANSMISION DEL SISTEMA PARA LA RCS Y LAS SUS, Y ADMINISTRACION DE LA CAPACIDAD DEL SISTEMA PARA MANTENER UN NUMERO MAXIMO DE SUS ACTIVAS PARA UN RENDIMIENTO MEJORADO DEL SISTEMA.
