Abstract

Se describe un método para un transmisor inalámbrico. El método comprende transmitir una señal de activación sobre un rango de frecuencia durante un intervalo de tiempo transmitiendo una primera parte de señal sobre un primer intervalo de frecuencia dentro del rango de frecuencia durante el intervalo de tiempo y transmitir una segunda parte de señal sobre un segundo intervalo de frecuencia dentro del rango de frecuencia durante el intervalo de tiempo. El primero y segundo intervalos de frecuencia no se superponen. La primera parte de señal tiene un primer valor de autocorrelación, y la segunda parte de señal está construida específicamente para proporcionar un segundo valor de autocorrelación de la señal que comprenda la primera y segunda partes de señal que sea menor que el primer valor de autocorrelación. La invención para resolver el problema de la detección falsa de una señal de activación modulada por MC-OOK en un sistema IEEE 802.11 usando OFDM.
