Abstract

Un receptor (75) para uso en una estación de comunicaciones de un sistema de CDMA en el que una pluralidad de estaciones de comunicación comunican unas con otras por encima de una interfaz de aire de CDMA que utiliza una pluralidad de canales y una señal piloto para la recuperación de la desviación de la portadora durante la recepción, comprendiendo el receptor; un filtro emparejado adaptativo (79) para recibir señales de comunicación de CDMA desmoduladas que producen una señal filtrada utilizando una señal de ponderación; un receptor de rejilla (101) para recibir señales de comunicación de CDMA en banda de base y una señal de falso ruido generada por un canal seleccionado no piloto y que produce una señal de ponderación de filtro; medios para refinar la señal de ponderación de filtro con una señal de corrección, produciendo la mencionada señal de corrección la señal de ponderación utilizada por el mencionado filtro emparejado adaptativo; un concentrador o desextendedor de canal (851, 852,85, , , ) para dicho canal seleccionado acoplado a la salida de dicho filtro emparejado adaptativo (79) para concentrar dicha señal filtrada utilizando el generador de señal de falso ruido para que dicho canal seleccionado produzca una señal de canal concentrada de dicho canal seleccionado; un concentrador (87) de canal piloto para un canal piloto acoplado a la salida de dicho filtro emparejado adaptativo (79) para concentrar dicha señal filtrada utilizando un generador de señal de falso ruido para que dicho canal piloto produzca una señal piloto reconcentrada de dicho canal piloto; un procesador de decisión firme (121) en asociación con un procesador de conjugado complejo para recibir la señal de canal de dicho canal seleccionado y que produce dicha señal de corrección; y un bucle en fase enclavada (133) que utiliza al menos dicha señal piloto concentrada para producir una señal de corrección de fase que se aplica para producir señales de canal de fase corregida.
