ABSTRACT:
A system for virtual time base direct synchronization in which a hopping sequence signal grossly synchronized with a received hopped base band has a fine synchronization correction performed by a virtual time shift of the hopping reference through first derivative subtraction of the phase of a hopped carrier signal, which in effect brings the hopping sequence signal into time alignment with the received hopped base band.
