Synchronization Signal Design for Cell Search in 3GPP-LTE HCN

[dietcha]

In this paper, the SSs for cell search are designed in multi-cell systems. The proposed SSs minimize the maximum magnitude of the cross-correlation function for a given length and the maximum number of supportable cells within a group is obtained for a given SS length and the maximum allowed cross-correlation value among the sequences. The simulation results show that the proposed signals have a distinct advantage in multi-cell environments.
