The characteristics analysis of hybrid bridge function sequence in multiuser UWB communication system

Basing on bridge function sequence and Walsh sequence, a special sequence called hybrid bridge function sequence is obtained. The paper focuses on the analysis of its orthogonal property and cross correlation property. Moreover, a formula of bit error rate (BER) is derived and hybrid bridge function sequence's performance in a multiuser UWB communication system is presented through theoretical analysis and simulations. The general characteristics of hybrid bridge function sequence are better than Walsh sequence's according to the analysis. All of these make up the shortages of the studies on the properties of hybrid bridge function sequence which provide basis for its application in the communication system.
