Hop overlay signal structure for including additional signaling channels in code division multiple access communication and navigation systems

   
   

A new signal format that allows sharing of spectrum with CDMA signals with a minimum amount of mutual interference and a maximum amount of processing gain. The method including the step of coherently frequency hopping a narrow band signal adapted to minimize interference with a main lobe of the CDMA code over the allocated bandwidth. A particular application of this provides a method for enabling a global positioning device adapted to receive an allocated bandwidth to directly acquire a to P(Y) code when an associated C/A signal is effectively jammed.
