Abstract

Se realiza un proceso de precodificación en una primera señal de banda base y una segunda señal de banda base para generar una primera señal de precodificación y una segunda señal de precodificación. Una señal piloto se inserta en la primera señal de precodificación y el cambio de fase se realiza en la segunda señal de precodificación. Se inserta una señal piloto en la segunda señal de precodificación con cambio de fase, y el cambio de fase se realiza además en la segunda señal de precodificación con cambio de fase con la señal piloto insertada.
