Abstract
In this paper, we propose and analyze ultra wide band (UWB) systems employing binary ZCD (zero correlation duration) code for wireless body area network (WBAN). When there are several wireless communication devices on a human body, multiple access interference (MAI) can occur. Hence, in order to reject MAI and enhance overall system performance, binary ZCD code is utilized as spreading code for UWB system. The performance is evaluated in terms of bit error rate (BER). From simulation results, it is confirmed that the UWB system with the ZCD code achieves better performance compared with that of pseudonoise (PN) code. The results of the paper can be applied to design and implementation of UWB systems for WBAN applications.
