Metodo y dispositivo de generacion de señales para generar señales a partir de multiples señales de banda base, multiples señales para la transmision en una banda de frecuencia comun y a una fecha hora comun

摘要

A transmission method simultaneously transmitting a first modulated signal and a second modulated signal at a common frequency performs precoding on both signals using a fixed precoding matrix and regularly changes the phase of at least one of the signals, thereby improving received data signal quality for a reception device.
