Abstract

PARA LA CORRELACION DE CODIGO DE RUIDO PSEUDOALEATORIO (PN), UN RECEPTOR GPS EMPLEA ENTRADAS DE SIGNO Y MAGNITUD COMO FUNCIONES DE PESO PARA CADA UNA DE LAS MUESTRAS DE FASE (I) Y FASE-CUADRATURA (Q) DE UNA PORTADORA MODULADA CON CODIGO DE RUIDO PSEUDOALEATORIO (PN). UN REGISTRO PROGRAMABLE R (82) PROPORCIONA CONTROL DE PESO EN MAGNITUD Y SIGNO DE LAS MUESTRAS A/D DE ENTRADA POR MEDIO DE UN MULTIPLEXOR (84) DE MUESTRAS CRUZADAS DE SALIDA, PARA LA ELIMINACION DE INTERFERENCIAS DE OTRAS SEÑALES DE RF, QUE INTERFIEREN CON LA PORTADORA DE RF MODULADA CON EL CODIGO PN QUE SE RECIBE . EL FACTOR DE PESO R DETERMINA SI LAS MUESTRAS A/D (ISALIDA, QSALIDA) PROCEDEN DE UN CONVERSOR A/D LINEAL O ADAPTATIVO. LAS SEÑALES (CIX7:0) DE REFERENCIA (IREF) EN FASE Y LAS SEÑALES (CQX7:0) DE REFERENCIA (QREF) DE FASE-CUADRATURA, PRODUCIDAS POR UN SISTEMA DE REFERENCIA DE CODIGO PN GENERADO INTERNAMENTE (48, 50, 52, 34, 36, FIG.3), SE PROPORCIONAN A UNA PLURALIDAD DE CORRELADORES/INTEGRADORES (88-102, 114-128 FIG.9) PARA LA CORRELACION CON LAS MUESTRAS I Y Q. EL APARATO CORRELA LAS MUESTRAS I Y Q OBTENIDAS DEL MUESTREO DE FRECUENCIA INTERMEDIA, O DEL MUESTREO BANDABASE DE LA PORTADORA MODULADA CON CODIGO PN QUE SE RECIBE.
