Abstract
Recently, with the growth of various sensor applications, the need of wireless communication systems which can support variable data rate is increasing. Therefore, advanced ZigBee (AZB) systems that support the various data rate under 250 kbps are proposed. However, the preamble structure for AZB systems causes the complexity increase of time synchronization circuits. In this paper, we propose preamble structure and time synchronization algorithm which can solve the problem of the complexity increase of time synchronization circuits. Implementation results show that the proposed time synchronizer for AZB systems include the logic slices of 6.92 k and, which are reduced at the rate of 62.3% compared with existing architecture.
