A new direct-sequence UWB transceiver based on Bridge function sequence

This paper reports how a novel direct-sequence UWB transceiver, utilizing Bridge function sequence as direct sequence, works in the wireless multipath environment. It is acknowledged that the Bridge function sequences have zero correlation zones (ZCZs) in their auto-correlation functions (ACFs). Due to the ZCZ properties of Bridge function sequences, the proposed direct-sequence UWB, using Bridge function sequence with properly chosen shift parameter, features a better performance on avoiding multipath interference than the one utilizing other spreading sequences without ZCZ. The theoretical justification of the proposed approach, together with its achievable performance in computer simulation, is presented in detail.
