Abstract
UN SISTEMA DE COMUNICACIONES DE ESPECTRO EXTENDIDO PARA USO SOBRE UN CANAL DE COMUNICACION, QUE INCLUYE UN GENERADOR DE CODIGO DE CHIP GENERICO TRANSMISOR (101), UN GENERADOR DE CODIGO DE CHIP DE MENSAJE TRANSMISOR (102), UNA PUERTA O EXCLUSIVA (103), UN COMBINADOR (104), UN TRANSMISOR (107), UN GENERADOR DE CODIGO DE CHIP GENERICO RECEPTOR (121), UN MEZCLADOR GENERICO RECEPTOR (123), UN FILTRO DE PASO DE BANDA GENERICO (125), UN GENERADOR DE CODIGO DE CHIP DE MENSAJE RECEPTOR (122), UN MEZCLADOR DE MENSAJE RECEPTOR (124), UN FILTRO DE PASO DE BANDA DE MENSAJE (126), Y UN DETECTOR SINCRONO (139). EL GENERADOR DE CODIGO DE CHIP GENERICO TRANSMISOR (101) GENERA UNA SEÑAL DE CODIGO DE CHIP GENERICA Y EL GENERADOR DE CODIGO DE CHIP DE MENSAJE TRANSMISOR (102) GENERA UNA SEÑAL DE CODIGO DE CHIP DE MENSAJE. EL ESPECTRO EXTENDIDO DE LA PUERTA O EXCLUSIVA (103) PROCESA DATOS DE MENSAJE CON LA SEÑAL DE CODIGO DE CHIP DE MENSAJE PARA GENERAR UNA SEÑAL DE ESPECTRO EXTENDIDO. EL COMBINADOR (104) COMBINA LA SEÑAL DE CODIGO DE CHIP GENERICO CON LA SEÑAL DE ESPECTRO EXTENDIDO. EL TRANSMISOR (107) TRANSMITE LA SEÑAL DE CODIGO DE CHIP GENERICO COMBINADA Y LA SEÑAL DE ESPECTRO EXTENDIDO, EN UNA SEÑAL PORTADORA (108) SOBRE EL CANAL DE COMUNICACIONES COMO UNA SEÑAL DE COMUNICACIONES DE ESPECTRO EXTENDIDO. EL GENERADOR DE CODIGO DE CHIP GENERICO RECEPTOR (121) GENERA UNA REPLICA DE LA SEÑAL DE CODIGO DE CHIP GENERICO. EL MEZCLADOR GENERICO (123) RECUPERA LA SEÑAL PORTADORA DESDE LA SEÑAL DE COMUNICACIONES DE ESPECTRO EXTENDIDO. EL GENERADOR DE CODIGO DE CHIP DE MENSAJES RECEPTOR (122) GENERA UNA REPLICA DE LA SEÑAL DE CODIGO DE CHIP DE MENSAJE. EL MEZCLADOR DE MENSAJES RECEPTOR (124) COMPRIME LA SEÑAL DE COMUNICACIONES DE ESPECTRO EXTENDIDO COMO UNA SEÑAL DE DATOS MODULADOS. EL CIRCUITO DE SEGUIMIENTO Y ADQUISICION (121) UTILIZA LA SEÑAL PORTADORA RECUPERADA PARA SINCRONIZAR LAS REPLICAS DE LA SEÑAL DE CODIGO DE CHIP GENERICO PARA LA SEÑAL PORTADORA RECUPERADA. EL DETECTOR SINCRONO (139) DEMODULASINCRONICAMENTE LA SEÑAL DE DATOS MODULADOS COMO LOS DATOS RECIBIDOS.
