Abstract

Se divulgan un sistema y un método mediante los cuales se pueden disminuir los efectos de los errores de tiempo de llegada. En una unidad móvil, como un dispositivo CDMA, se genera un pulso de correlación cuando un código transmitido coincide con un código de referencia almacenado. En ausencia de efectos de múltiples trayectorias, los pulsos de correlación se generan en respuesta a la detección de múltiples transmisiones del código de referencia desde múltiples transmisores. Sin embargo, los efectos de múltiples trayectorias distorsionan los pulsos de correlación generados, lo que lleva a errores en las mediciones del tiempo de llegada. La presente invención calcula el ancho de los pulsos de correlación y determina un factor de corrección de retraso sobre la base del ancho del pulso. El factor de corrección de retraso se agrega al tiempo de retraso medido para proveer un tiempo de retraso más preciso y por lo tanto permitir mediciones de localización más precisas sobre la base del tiempo de llegada. En otras realizaciones, se pueden utilizar otros factores de senal para aplicar factores de corrección de retraso. La unidad móvil, u otro ente para determinar el posicionamiento (PDE) puede realizar la determinación de localización en sí. Asimismo, el sistema es capaz de aplicar factores de corrección a senales de tiempo de llegada recibidos desde un satélite de un sistema de posicionamiento global
