An information acoustic wave wireless data transmission system

Abstract

The present application relates to a kind of information sound wave wireless data transmission systems, including transmitting end, air channel and receiving end.Transmitting end is used to the information to be transmitted is encrypted and modulated processing, and the signal after processing is converted into sound wave signal and is transmitted;Sound wave signal is propagated to receiving end by air channel.Receiving end is used to receive sound wave signal, and the sound wave signal is demodulated and decrypted processing, to recover original information.Through the above structural arrangement, complete information sound wave wireless transmission link is formed, realizes the wireless transmission of information under non-electromagnetic communication condition, is suitable for electromagnetic communication limited or not suitable for using electromagnetic signal application scenario.
