| Abstract: | This paper investigates the specific role of time-hopping sequences in the time-hopping pulse position modulation ultrawideband system and its effect on the BER performance of the system. A novel family of time-hopping sequences that provides the optimal hamming correlation properties is constructed. Computer simulation shows that the UWB system employing the constructed time-hopping sequence can reduce the multi-access interference and accordingly better performance can be gained as compared with the other ones. |
