Abstract
Un método (100) de transmisión de diversidad que incluye formar, desde una señal de transmisión, una primera señal (A) con una primera identificación y una segunda señal (B) con una segunda identificación que son transmitidas por medio de antenas separadas, por lo que se usan más de dos antenas (1, 2, 3, 4), caracterizado porque en una primera operación (110), las antenas (1, 2, 3, 4) son divididas en un primer grupo de antenas (1, 3) y un segundo grupo de antenas (2, 4), porque en una segunda operación (120), la primera señal (A) es transmitida por medio del primer grupo de antenas (1, 3) y la segunda señal (B) por medio del segundo grupo de antenas (2, 4), porque en una operación posterior (160), se forman al menos una vez un nuevo primer grupo de antenas (1, 4) y un nuevo segundo grupo de antenas (2, 3) y, porque a continuación, la segunda operación (120) es repetida.
