Abstract: A method and system for wireless communication are provided. The method for wireless communication comprises following steps. The master device encodes an information code sequence including a communication demand into a wake-up sequence and transmits the wake-up sequence to each slave device continuously within a preset time period. The slave device receives the wake-up sequence in the detecting period, decodes the wake-up sequence, judges the correlation between the at least two parts, determines whether to be waken-up according to a judging result and performs corresponding response according to the decoding information. When implementing the technical solution in this invention, the power consumption in the wireless communication is reduced, the encoding efficiency is enhanced and the communication process is simpler.

Abstract: A method and system for wireless communication are disclosed. The method comprises: the master device generates a sequence code through a specific encoder and transmits the sequence code to each slave device continuously within a preset period according to the communication demand, wherein the specific encoder is a feedback shift register constructed by a specific polynomial, of which the coefficients and the order are in correlation with the communication demand while all of the coefficients and initial values are not equal to 0 at the same time; the preset period is greater than or equal to the sum of a sleeping period and a detecting period of the slave device, which constitutes a sleeping-and-waking cycle; the slave device receives a continuous section of the sequence code in the detecting period, decodes the sequence code through a decoder corresponding to the encoder, and performs corresponding operation according to the decoding result.
