摘要：
Time-hopping (TH) techniques have received increasing attention, as ultra wide band (UWB) impulse radio (IR) is proposed. The correlation properties of TH sequences have an important effect on the performance of IR communication system. This paper analyses the correlation properties of TH sequences. The definition of the correlation function of TH sequences is given. The upper and lower limits of correlation value of time-hopping sequences are obtained. At last, the way to improve the correlation property of TH sequences is obtained. By this means, the maximum correlation value of TH sequences will be deceased to the half of original value.
