Abstract :
In the construction of zero correlation zone (ZCZ) sequences, as the length of the interference free window (IFW) increases, fewer sequences are available and hence their utility in multiuser systems diminishes. To address this issue, it is shown that, for a given IFW, it is possible to design multiple sets of ZCZ sequences which are mutually orthogonal.
