Abstract

Un método para transmitir una señal de entrenamiento en un sistema de red de área local inalámbrica (WLAN) incluye generar una o más primeras señales de entrenamiento para una primera estación de destino y una o más segundas señales de entrenamiento para una segunda estación de destino aplicando una matriz de mapeo P a una secuencia de generación de señal de entrenamiento, mapear las primeras señales de entrenamiento y las segundas señales de entrenamiento a una pluralidad de antenas de acuerdo con la matriz de mapeo de antena, y realizar la transformada de Fourier rápida inversa (IFFT) en cada una de las primeras señales de entrenamiento y las segundas señales de entrenamiento mapeadas para la pluralidad de antenas y transmitir las señales de entrenamiento a través de la pluralidad de antenas.
