Lower bounds on correlation of spreading sequenceset with low or zero correlation zone
Xiaohu Tang, Pingzhi Fan, Shinya Matsufuji · Electronics Letters · 2000
To eliminate multiple access interference, approximately synchronised code division multiple access systems employ spreading sequence sets with low or zero correlation zone properties. The authors present a method for deriving the bounds on the correlation of a polyphase sequence set concerning the size, length and low or zero correlation zone based on Welch's technique.
