Abstract

Un método para determinar un precodificador a partir de un primer libro de códigos, en donde dicha determinación del precodificador comprende medir en un conjunto de puertos de antena sometidos a formación de haces, y en donde los precodificadores en el primer libro de códigos comparten uno o más componentes comunes con precodificadores en un segundo libro de códigos de varios haces y en donde determinar los precodificadores a partir del segundo libro de códigos comprende medir en un conjunto más grande de puertos de antena, típicamente no precodificados.
