Abstract :
Novel ternary preferred pairs (TPPs) that have a greater zero correlation duration (ZCD) of (0.75 N+1) for a period N are constructed by applying selected zero padding to binary preferred pairs with ZCD of (0.5 N+1). A chip-shift operation is then performed to derive new ternary ZCD sequences that have superior family size to that of binary ZCD sequences
