摘要: In this paper, we present a low-complexity cell-search algorithm and architecture for secondary synchronization signal in 3GPP-LTE downlink systems. Differential correlations are computed to remove common channel effects so that two sets of synchronization signals can be combined to obtain enhanced detection quality. To achieve low complexity, we further adopt one-bit quantization and exploit the properties of limited offset in the indices of the two maximal-length sequences. The arithmetic complexity of the proposed algorithm is significantly reduced while attaining similar detection performance comparable to the conventional schemes. Finally, hardware architecture of the proposed algorithm is presented to demonstrate feasibility and efficiency in the implementation. 其他題名: LWC 出版者: IEEE 出版日期: 2012-08-01 出處: IEEE wireless communications letters, 2012-08, Vol.1 (4), p.280-283 資源來源: IEEE Xplore 識別號: ISSN: 2162-2337 識別號: EISSN: 2162-2345 識別號: DOI: 10.1109/WCL.2012.041612.110263 識別號: CODEN: IWCLAF
