The present invention discloses a method for generating a zero correlation zone code. The method comprises the following procedures: combining a linear feedback shift register sequence (m sequence) with initial maximum length with sequence (1) to basic code; and expanding the basic code to generate the zero correlation zone code. The invention additionally discloses a method for generating and transmitting the spectrum spreading code with the zero correlation zone code. The method comprises the following procedures: expanding the basic code generated with the initial m sequence and sequence (1) for generating the zero correlation zone code; and inserting a nonzero protecting interval in the zero correlation zone code, generating and transmitting the spectrum spreading code. The invention also discloses a method for generating and receiving the spectrum spreading code with the zero correlation zone code. The invention further respectively discloses a device for generating the zero correlation zone code, a device for transmitting the spectrum spreading code and a device for receiving the spectrum spreading code. The method of the invention can increase the number of the available code of the generated zero correlation zone code thereby increasing the number of the available code of the transmitting spectrum spreading code and receiving spectrum spreading code generated with the zero correlation zone code.
