发明名称 PN code synchronizing method and transmitter and receiver in spread spectrum communication systems
摘要 <p>A PN code synchronizing method in spread spectrum communication systems of the present invention calculates a matrix H based on tap locations of a PN code generating shift register, also calculates an internal status of the PN code generating shift register at a time t+M by multiplying an internal status of the PN code generating shift register at a time t by M-th power of the matrix H, and transmits the internal status of the PN code generating shift register at a time t+M to reception side through a synchronous channel. in reception side, a PN code generating shift register therein is set based on the internal status of the PN code generating shift register at a time t+M. <IMAGE></p>
