Abstract

Optimization of structure and scanning steps of scan codes is a key to improving recognition efficiency of scanning anti-collision algorithm for antenna line devices (ALD). By studying the influence of combining the mask and matching code on the scanning time, the mask extension by bit can be achieved to
approach the device UID so that the scanning time is reduced. Meanwhile, from layered analysis, optimal bit number is obtained in the mask extension. The two-bit mask extension has been shown to be optimal. Accordingly, scan codes are constructed, and a scanning anti-collision algorithm for ALD based on the two-bit mask extension is proposed. The simulation analysis shows the good scanning performance of the proposed algorithm.

Key words： antenna interface standards group (AISG) protocol; remote electrical tilt; device scanning; algorithm performance
