Abstract

Se proporcionan aparatos para comunicación inalámbrica; el aparato incluye un procesador configurado para generar un paquete para transmisión a través de una señal inalámbrica; el paquete es generado para transmisión sobre un ancho de banda de 1 MHz utilizando al menos un símbolo de multiplexión por división de frecuencia ortogonal (OFDM) que comprende 32 subportadoras descritas por índices de -16 a 15, en donde cada una de las 32 subportadoras tiene una energía de constelación promedio; el aparato además incluye un transmisor configurado para transmitir el paquete a través de la señal inalámbrica de manera que cada energía de constelación promedio para subportadoras que tienen índices -8 a -1 y 1 a 8 se desvía no más de +-4 dB de un promedio general de las energías de constelación promedio sobre subportadoras que tienen índices de -8 a -1 y 1 a 8, y cada energía de constelación promedio para subportadoras que tienen índices de -13 a -9 y 9 a 13 se desvía no más de +4/-6 dB del promedio general.
