OCDMA CODE TRACKING SYSTEM HAVING PHANTOM CARRIER SIGNAL |
摘要 |
An OCDMA communication system in which channel signals are bandwidth spread according to a PN code and each channel is identified by a selected one of a set of RW code accesses. The set of RW codes is reduced by a predetermined one (preferably RWo). Each transceiver has acquisition and tracking circuitry which search for a null (e.g., the unsent RW access code) falling lower than a predetermined threshold value and synchronizing tracking on detection of the null.
