Abstract
A transmission method for transmitting a first modulated signal and a second modulated signal in the same frequency at the same time. Each signal has been modulated according to a different modulation sheme. The transmission method applies precoding on both signals using a fixed precoding matrix, applies different power change to each signal, and regularly changes the phase of at least one of the signals, thereby improving received data signal quality for a reception device.
Claims (10)
1 . A transmitting apparatus comprising:
at least one processor configured to generate a first signal and a second signal from a same data on which error correction coding has been performed; and
a receiver configured to receive control information, wherein
the at least one processor is further configured to:
turn on or off a phase change only on the second signal to be transmitted according to the control information; and
control a first transmitter and a second transmitter to transmit the first signal and the second signal in a predetermined frequency band at a same time, respectively, the first transmitter and the second transmitter being physically separate devices from the transmitting apparatus.
2 . A receiving apparatus comprising:
at least one processor configured to generate control information indicating whether a phase change is turned on or off;
a transmitter configured to transmit the control information to the transmitting apparatus according to claim 1 ; and
a receiver configured to receive the first signal and the second signal from the first transmitter and the second transmitter in the predetermined frequency band at the same time, respectively.
