In this paper multilevel complementary pairs of sequences without limitation in length and the generation of multilevel Loosely Synchronized (LS) sequences with flexible Zero Correlation Zones (ZCZ) length are proposed. The existence of efficient correlators and the fewer restrictions on the length of the multilevel LS sequences compared to binary LS ones, makes them worthwhile for their application to Local Positioning Systems (LPS).
