Abstract

Técnicas para facilitar la estimacion de la respuesta de la frecuencia de un canal inalámbrico en un sistema de OFDM. El método y los sistemas permiten la combinacion de la informacion de la senal a través de multiples canales de comunicacion en uno o más retardos de tap de canal, a efectos de determinar taps adecuados para la informacion del canal.
