Abstract
For all DS-CDMA based satellite navigation systems which have been emerging these days, it is required to design a set of spreading sequences to eliminate both multi-access and multi-path interference. In a typical CDMA system, it is well-known that it is highly impossible for the spreading sequences to possess both ideal cross-correlation and ideal auto-correlation properties simultaneously. Recently, Zero Correlation Zone (ZCZ) sequences based on the concept of generalized orthogonality (GO), with well-defined zero correlation zone property has been introduced. In this paper, we described the Zero Correlation Zone (ZCZ) sequence algorithm and its possibility to use in satellite navigation system has been discussed and presented.
