Abstract

Métodos y aparatos que utilizan la transformada discreta de Fourier de las respuestas del dominio del tiempo para generar pesos formadores de haces para las comunicaciones inalámbricas. Además, en algunas formas de realizacion pueden utilizarse subportadores de frecuencia que constituyen una cantidad inferior a la totalidad de los subportadores de frecuencia asignadas para la comunicacion a un usuario, para generar las pesos formadores de haces.
