Abstract

Se describe un método de transmisión que transmite simultáneamente una primera señal modulada y una segunda señal modulada en la misma frecuencia, en donde una unidad de multiplicación para ponderación da precodificación multiplica una señal de banda base después de una primera correlación y una señal de banda base después de una segunda correlación por una ponderación de precodificación, y da salida a la primera señal modulada y la segunda señal modulada, con la ponderación de precodificación siendo cambiada regularmente.
