Abstract

La presente tiene muchos aspectos. Un aspecto del presente es realizar ecualización utilizando un procedimiento de ventana deslizante. Un segundo aspecto vuelve a utilizar información derivada de cada ventana para su uso por parte de una ventana subsiguiente. Un tercer aspecto utiliza un procedimiento basado en transformada de Fourier discreta para la ecualización. Un cuarto aspecto se refiere al manejo de sobremuestreo de las señales recibidas y respuestas de canal. Un quinto aspecto se refiere al manejo de antenas de recepción múltiples. Una sexta forma de realización se refiere al manejo tanto de sobre-muestreo como de antenas de recepción múltiples.
