<p>Disclosed in the embodiment of the invention are a method and device for sending and receiving data. The method for sending data comprises: data bit 1 is transmitted in a periodic waveform within the period T1, data bit 0 is transmitted in the periodic waveform within the period T2, and the T1 is not equal to T2; and according to the bit sequence of data to be sent, the corresponding periodic waveforms are sent continuously. According to the method and device for sending and receiving data disclosed by the embodiment of the invention, a receiving terminal can determine the bit sequence of the received data according to the periods of the periodic waveforms, so that the complicated process of detecting a duty ratio in the prior art is avoided, and the load and the cost of the receiving terminal are reduced.</p> |
