Signal transmission system, transmitting device, receiving device, electronic device, and signal transmission method

A signal transmission system comprising:

• a transmitting side local oscillating section configured to generate a carrier signal at a carrier wave frequency, a carrier frequency band being a frequency band of the carrier signal;
• a modulation section configured to modulate a data signal into a modulated signal;
• a frequency section configured to frequency convert the modulated signal from a baseband to the carrier frequency band to generate an electric signal;
• an amplifying section configured to amplify said electric signal, an amplified signal being said electric signal that has been amplified, the amplifying section having a use band set to shift the center of the band of said amplified signal, thus creating an asymmetry of the band of said amplified signal with respect to said carrier wave frequency;
• and
• a transmission medium receiving said amplified signal and propagating said amplified signal, wherein a transmission characteristic of said transmission medium is calculated in advance,
• wherein said amount of said shift to the center of the band of said amplified signal is dependent upon said transmission characteristic of said transmission medium calculated in advance.
