前导序列 meaning in English

leader sequence
leading sequence

Due to the needs for the flat spectrum character , the leading sequence requires high self - correlation . the author selected a series of sequences whose highest peek to second highest peek ratio is big , from a series of " m " sequences . then , the optimized leading sequences were judged according to glf , the sequences which have lower glf would be more proper for the estimation
首先，作者提出搜索的标准，根据前导序列要有平坦的谱特性，从而要有好的自相关性，从一种m序列中找出最大峰与次大峰比例较大的一些序列，然后根据增益损耗因子来判决最佳前导序列，增益损耗因子越小的序列越适于估计。
This thesis mainly discusses the techniques of channel estimation in frequency domain , which utilizes the optimized leading sequence . an enhanced method for searching optimized leading sequences is introduced based on existing documents . this method can decrease the errors and make the searching and caculating easier
本论文主要讨论用最佳前导序列在频域中进行信道估计的问题，在前人的基础上提出一种改进型的搜索最佳前导序列的方法，可使得估计误差减小且便于搜索计算，仿真验证了算法的有效性。
