Summary:In this paper, we propose a synchronization scheme based on partial Zadoff-Chu sequences for cooperative MIMO systems. In the proposed training sequence design, partial Zadoff-Chu sequences are placed on disjoint sets of subcarriers in an interleaved manner. Such an arrangement not only guarantees frequency-domain training signal separation, but also produces separable time-domain training signals to lessen the mutual interference among the training signals in both the frequency domain and the time domain. Furthermore, propagation delays and carrier frequency offsets can be estimated solely in the time domain, while they are estimated in the time domain and the frequency domain, respectively, in most existing synchronization schemes for cooperative MIMO systems. The proposed training sequences also enjoy good auto-correlation and cross-correlation properties that improves synchronization performance.
