| Research Abstract |
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.
