Assignee: MITSUBISHI ELECTRIC CORPORATION
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A transmitting apparatus comprising:
a first signal generator configured to generate, based on data, a first signal to be transmitted according to single carrier block transmission;
a second signal generator configured to generate, based on a known signal, a second signal to be transmitted according to orthogonal frequency division multiplex transmission;
a switcher configured to receive the first signal and the second signal, to select and output the second signal in a first transmission period, and to select and output the first signal in a second transmission period notified by a receiving apparatus; and
at least one antenna configured to transmit the first signal and the second signal output from the switcher, and further comprising:
a controller configured to control the second signal generator such that, in the first transmission period, the known signal is a reference signal used for demodulating the first signal in the second transmission period and is arranged in discontinuous frequency bands assigned by the receiving apparatus for transmitting the known signal from the transmitting apparatus among frequency bands available in the orthogonal frequency division multiplex transmission.
