International Telemetering Conference Proceedings / October 26-29, 1992 / Town and Country Hotel and Convention Center, San Diego, California / New tracking/control system requirements demand that the
present DFCS/GRDCUS/MTACS data link bit rate be increased. A
possible method for achieving this increase is to select two
additional 31-bit chip code patterns that are orthogonal to
the present chip codes, and to each other. This method will
not require any more bandwidth than the present 10 MHZ used.
This method suggest that each of the four chip code patterns
are assigned a two bit value ie: 00, 01, 10, 11. At present,
the two correlated chip codes represent data in a pulse
position method. No data is contained in which of the two
chip codes actually correlated. This new method suggest each
of the four chip code patterns will still perform the pulse
position modulation and provide two additional bits of data.
These additional two bits of data will up the data rate of
the link by 100 percent.
