Combinatorial Constructions for UWB Time-Hopping Sequences

在同步型UWB的情况下，UWB序列与跳频序列是等价的问题。2008年，我们与香港科技大学的丁教授和其他一些日本人一起学习。我们得到了一些关于跳频序列的新的递归构造和利用一些特殊类型的线性码的有向构造的一些结果。我们知道，同步型UWB序列正是循环多结构设计的一种。因此，我们花了时间在多结构设计的统一施工上。

In the case of synchronized type UWB, the UWB sequences are equivalent problems to Frequency Hopping sequences. In 2008, we jointly studied with Professor Ding of Hong Kong University of Science and Technology and some other Japanese. We had some results on new recursive constructions of FH sequences and directed constructions using some special type linear codes. We knew that synchronized type UWB sequences are exactly one of the cyclic multi-structured designs. Therefore we spent time on unified constructions for the multi-structured designs.
