    摘要:

    分析了遥控电调倾角天线设备扫描机制及搜索识别过程,确定了遥控电调倾角天线设备搜索算法的性质和类型,同时提出了扫描周期在4种反馈状态下算法的应对策略,对优化和改进算法搜索效率提供了理论依据。算法实现采用对各搜索深度分层分析的方法,研究各扫描周期下,相同的掩码放开位数在设备搜索过程中的时间消耗情况,获得较优的掩码放开步骤,并针对AISG2.0协议,提出了基于重复扫描的混合掩码放开位的设备搜索算法。仿真和实践对比证明,该算法在有效降低设备识别时间的同时,提高了设备搜索效率。

    Abstract:

    Scanning mechanisms and recognizing process of remote electrical tilt antenna are analyzed, and property and type of remote electrical tilt antenna device searching algorithm is concluded, and 4 feedback states of devices in a scan cycle are summarized and the coping methods are presented, so to provide theoretical basis for an algorithm to improve and optimize the device searching efficiency. Layered analysis method to the various searching depth is taken in the algorithm realization and the impacts on the total scanning time with different number of the devices and mask shift bits are researched, and design method of more optimized algorithm is achieved, and device searching algorithm based on repeated scanning and the hybrid mask shift bits on AISG2.0 protocol is put forward. Simulation and practice show that the proposed algorithm can effectively reduce RET device recognition time and increase device search efficiency.
