Abstract

Se describe un receptor el cual recibe y procesa una radio recibida vía un canal de radio selectivo de frecuencia de un transmisor que emplea una pluralidad de antenas de transmisión. El receptor determina, sobre la base de la señal recibida, coeficientes de precodificador complejos y retardos de precodificadores de retardo espacial respectivos para cada capa y antena de transmisión en el transmisor para lograr una propiedad predefinida para una comunicación sobre el canal de radio, modelando o definiendo cada precodificador de retardo espacial por la antena de transmisión asociada una pluralidad de filtros cíclicos que retardan y ponderan una señal que va a ser transmitida con los retardos de precodificador y coeficientes de precodificador complejos correspondientes, respectivamente y retroalimenta al transmisor los retardos determinados explícita o implícitamente y los coeficientes de precodificador complejos determinados explícita o implícitamente, precodificando el transmisor las señales que van a ser transmitidas al receptor usando los retardos de retroalimentación y los coeficientes de precodificador complejos.
