摘要:	摘要： A time-domain (TD) channel estimation (CE) technique is proposed in this paper to enhance the CE performance of IEEE 802.11p standards in cases when the pilot density is insufficient to accurately estimate channel states in rich-scattering environments. This technique is based on a least squares (LS) algorithm and assisted from Zadoff-Chu (ZC) sequences arranged into the symbol prefix and training preambles. The channel conditions tested in this paper were comprehensively simulated in urban, suburb and express-way scenarios. 其他題名： Telecommun Syst 出版者： Boston: Springer US 出版日期： 2013-04 出處： Telecommunication systems, 2013-04, Vol.52 (4), p.1731-1742 資源來源： ABI/INFORM Collection 版權： Springer Science+Business Media, LLC 2011 版權： Springer Science+Business Media New York 2013 識別號： ISSN: 1018-4864 識別號： EISSN: 1572-9451 識別號： DOI: 10.1007/s11235-011-9480-x
