FPGA implementation of WSLCE sequence for GNSS applications

Pseudo Random Sequence is used in Spread spectrum system. One such PRN sequence, SLCE (Sidelnikov, Lempel, Cohn, Eastman), is studied in this paper. The SLCE sequence is used in Global Navigation Satellite System(GNSS) as the spreading sequence. By studying the Weil Sequence along with SLCE sequence, a class of Binary PRN sequence called Weil-SLCE(WSLCE) is implemented on Kintex 7 FPGA. The auto correlation, cross correlation and other complexities of the WSLCE sequence are examined. This sequence is intended to be used in the current GNSS as well as in the future GNSS which are still in development stage.
