PRN sequence design based on Concatenation of Weil Sequences (CWS)

Pseudo-Random Noise (PRN) codes are widely used in Global Navigation Satellite System (GNSS). These PRN codes have properties like, Randomness, Balance, Correlation, family size, etc., and hence make it necessary to carefully design the codes suitable for particular application. Most of the GNSS adopt Linear Feedback Shift Register (LFSR) based methods due to the ease of implementation in hardware. In this research work, the current research puts forth a new technique based on concatenation of Weil Sequences (CWS), and the proposed sequences are found to provide 2 to 4 dB better correlation than the existing state-of-the-art sequences used in satellite navigation systems. The sequences generated using the proposed method are analyzed in detailed manner and the outputs confirm the suitability of the proposed method for use in GNSS systems.
