The present application relates to the field of wireless communication, and especially relates to a low complexity concatenated modulation method for multi-mode symbol serial number modulation, a physical layer security transmission method and a computer readable storage medium. The low complexity concatenated modulation method for multi-mode symbol serial number modulation forms a concatenated multi-mode symbol serial number modulation mode. When processing an OFDM symbol period block, all frequency domain subcarriers are first divided into subblocks, each subblock is taken as a basic modulation unit, high-dimensional serial number modulation of one subblock is reduced to low-dimensional serial number modulation of two micro-subblocks in two-level concatenated serial number modulation, and the calculation complexity of modulation and demodulation at the transmitting and receiving ends is greatly reduced. Furthermore, in the physical layer security transmission, the dimension size of the first modulated micro-subblock is taken as a physical layer security transmission parameter, and dynamic change will make the same group of information bits get different output results after multi-level serial number modulation, reduce the cracking possibility, and realize the physical layer security transmission.
