Spread spectrum communication method |
摘要 |
The spread spectrum communication system based on the CDMA-FDD system in which two or more carrier frequencies can be selectively used in the present invention is equipped with the section that carries out handover between base stations with the same carrier frequency switched by a spreading code from a carrier frequency used in communication and the section that switches carrier frequencies within the handover base station after handover between base stations is completed. This allows the mobile station to carry out handover between base stations with different frequencies without the mobile station transmitting/receiving two or more carrier frequencies simultaneously.
