Abstract
In this paper, ternary ZCD (zero-correlation duration) sequences are proposed as the new spreading codes. Novel ternary ZCD sequences sets are generated by carrying out a chip-shift operation of the ternary preferred pairs (TPP) with ZCD of (0.75 N-1) chips. Proposed ternary ZCD sequences have superior family size than the binary ZCD sequences and they are effective for approximately synchronized (AS) CDMA
