摘要：
Recently, ultra-wideband (UWB) communications systems for personal communications and wireless LANs became an important area of research. It was shown that perfect difference set sequences have a flat spectrum and although there was only one sequence, a set of sequences was obtained with values in {-1,1} and with perfect correlation. This paper presents an explicit construction of perfect difference sets divisible by four.
