Abstract

La invención aquí descrita presenta un sistema y método para lograr superar las distorsiones y afectaciones introducidas por las canales altamente variantes de una o varias antenas tanto en el transmisor como en el receptor. A diferencia de cualquier invención existente que opera en las mismas condiciones, este aparato utiliza una técnica de recepción completamente novedosa basada en el concepto de trayectorias virtuales en la que no se requieren cálculos iterativos o solución de sistemas lineales en tiempo de operación, ahorrando así una cantidad considerable de operaciones. El receptor de este aparato logra convertir las variaciones rápidas del canal en antenas virtuales, logrando así un incremento considerable de la relación señal a ruido-interferencia. El desempeño que obtiene en términos de inmunidad de ruido es mucho mejor que cualquier técnica encontrada hasta el momento y además requiere una cantidad mucho menor de cálculos en el receptor.
