Abstract

Un metodo para comunicar estimaciones de canal sobre una pluralidad de subportadores entre un dispositivo transmisor y un dispositivo receptor. El dispositivo transmisor determina una estimacion de canal sobre una pluralidad de subportadores y entonces codifica las estimaciones de canal en al menos una forma de onda de canal codificada. Entonces el dispositivo transmisor transmite al menos una forma de onda de canal codificada al dispositivo receptor.
