1. A transmitting device comprising:
a processor configured to:
generate a first precoded signal and a second precoded signal by performing a precoding process on a first baseband signal and a second baseband signal, respectively;
generate a first signal by inserting a pilot signal into the first precoded signal;
apply a phase change of i×Δλ to the second precoded signal, where i is a symbol number and an integer that is greater than or equal to 0, and Δλ=π−π/m radians, where m is an integer that is greater than 3;
insert a pilot signal into the second precoded signal applied with the phase change; and
generate a second signal by applying a phase change to the second precoded signal applied with the phase change and inserted with the pilot signal, and
a transmitter configured to transmit the first signal and the second signal.
