Abstract
A transmission method includes generating a first precoded signal and a second precoded signal by performing a precoding process on a first baseband signal and a second baseband signal, outputting a third signal by inserting a pilot signal into the first precoded signal, outputting a fourth signal by applying a first phase change to the second precoded signal, outputting a fifth signal by inserting a pilot signal into the fourth signal, and outputting a sixth signal by applying a second phase change to the fifth signal.
Claims2
A transmission apparatus comprising:
- a signal processing circuit that, in operation, generates control signals and data streams, the control signals being generated by performing a cyclic shift diversity scheme, the data streams being phase-rotated by first signal processing and phase-adjusted by second signal processing;
- and
- a transmitter that, in operation, transmits the control signals and the data streams through multiple antennas in a single carrier mode, wherein
- in the first signal processing, data symbols included in each of the data streams are phase-rotated using a phase rotation value that is defined per data symbol included in the data symbols, according to an order of the data symbols,
- in the second signal processing, the data symbols included in each of the data streams are phase-adjusted using a phase adjustment value that is defined per data stream included in the data streams, and
- the control signals are generated from control data having a field indicating whether the data streams are modulated using the single carrier mode or not.
