Embodiment Construction
[0063] The signal generation method of the interference-free quasi-synchronous code division multiple access communication system of the present invention comprises the following steps:
[0064] From having zero correlation zone length Z CZ Select as the spread code word of the spread code in the spread sequence code group of the spread spectrum;
[0065] performing spread-spectrum modulation processing on the input original data by using the selected spread-spectrum codeword, thereby generating a spread-spectrum modulated signal;
[0066] Wherein, the spreading sequence code group is composed of a Z-complementary sequence set Z-CS (M, 2, N, Z) whose sequence length is N, the number of complementary sequences is 2, the number of companions is M, and the length of the zero-correlation zone is Z. ) and the second-order Walsh-Hadamard orthogonal matrix.
[0067] The generation of the spreading sequence code group with zero correlation region of the present invention will be des...
