| 1. An electronic device comprising:
a radio transmitting part which transmits, by radio, transmission data having a real transmission data portion and a preamble
portion mixed, the preamble portion constituted by pseudo noise signals arranged in a given pattern;
a radio receiving part near the radio transmitting part, which receives transmission data transmitted from the radio transmitting
part and has a phase-adjusting control part, the phase-adjusting control part adjusting a phase of a received local oscillator
output based on the pseudo noise signals of the preamble portion; and
a wire communication part which communicates a timing of transmitting the preamble portion in the transmission data transmitted
by the radio transmitting part to the radio receiving part by wire.
