Synchronization for DSSS transmission system using jittered pilot code

摘要

The invention relates to pilot assisted direct sequence spread spectrum links. Fine code synchronisation generally requires either multiple receiver correlators (early/prompt/late) or jittered receiver correlators (Tau dither). The present invention removes the need for either by jittering the pilot code at source so that the receiver only needs to examine a single code phase and can generate a fine code phase steering signal from the difference between the pilot energy measured when transmitted early and measured when transmitted late.
