Method And System For Generating Spreading Codes Based On Interleaved Z4 Linear Sequences For Navigation Systems
Abstract: A system and method is provided for generating a pseudorandom sequence family suitable for satellite-based navigation systems. The family is derived by suitably interleaving a family of binary Z4-linear sequences and is referred to as a family of Interleaved Z4-linear (IZ4) spreading codes. The IZ4 family is efficient in terms of even and odd autocorrelation and cross-correlation as well as balance properties and compares very favourably with sequences employed by GPS and Beidou systems as judged by most common performance measures. The proposed system and the method do not need either padding or puncturing of bits to achieve the mandated period of 10230. Efficient shift-register techniques can be employed to generate the spreading codes.
