1. a data transmission method for uplink, is characterized in that, comprising:

  • Take cycle as the periodic waveform transmission data bit 1 of T1, take cycle as the periodic waveform transmission data bit 0 of T2, described T1 is not equal to described T2;

    According to the bit sequence of data to be sent, the continuous described periodic waveform sending correspondence, the bit sequence of described data to be sent comprises successively;

    synchronous head, multiple character to be transmitted and synchronous tail, wherein, the bit number M of described synchronous head is more than or equal to 2 and each bit value is identical, the bit number N of described synchronous tail is more than or equal to 2 and each bit value is identical, each described character to be transmitted comprises successively;

    the start bit of at least 1 bit, the data bit of at least 1 bit and the position of rest of at least 1 bit, the bit value of described start bit is identical and be not equal to the bit value of described synchronous head, the bit value of described position of rest is identical and be not equal to the bit value of described synchronous tail.
