Abstract

MÉTODOS Y SISTEMAS PARA MEJORAR UNA SEÑAL DE COMUNICACIÓN MAGNÉTICA. EL MÉTODO PARA MEJORAR UNA SEÑAL DE COMUNICACIÓN MAGNÉTICA, COMPRENDE LOS PASOS DE RECIBIR UNA SEÑAL DE COMUNICACIÓN MAGNÉTICA QUE CONTIENE DATOS E INTERFERENCIA DE COMUNICACIÓN MAGNÉTICA A TRAVÉS DE UNA PLURALIDAD DE ELEMENTOS DE ANTENA; MEDIR LAS AMPLITUDES RELATIVAS DE LA SEÑAL DE COMUNICACIÓN MAGNÉTICA RECIBIDA DE CADA UNO DE LOS ELEMENTOS DE ANTENA, MEDIR LA INTERFERENCIA CONTENIDA EN UNA PLURALIDAD DE SEÑALES RECIBIDAS DE CADA ELEMENTO DE ANTENA DURANTE UN INTERVALO DE TIEMPO EN EL QUE LOS DATOS DE COMUNICACIÓN MAGNÉTICA ESTÁN AUSENTES EN LAS SEÑALES RECIBIDAS; CALCULAR UNA PLURALIDAD DE PONDERACIONES INDICATIVAS DE LAS AMPLITUDES MEDIDAS Y LA INTERFERENCIA MEDIDA, Y GENERAR UNA SUMA PONDERADA DE SEÑALES DE COMUNICACIÓN MAGNÉTICA RECIBIDAS DE CADA ELEMENTO DE ANTENA USANDO LAS NONDERACIONES CALCULADAS.
