Abstract :
A generalised method for constructing binary preferred pairs with zero-correlation duration (ZCD) of (N/2+1) chips is proposed. Binary sequence sets with ZCD and enlarged family sizes are generated by carrying out a chip-shift operation for the preferred pairs. The properties of the proposed sequences are effective for approximately synchronised CDMA systems.
