摘要:

针对传统RSSI室内测距技术易受环境因素影响问题,提出测距补偿算法,利用算法补偿环境因素造成的测距误差,并利用均值平滑法来处理同一点接收到的多个RSSI值,以减小RSSI值的测量波动。通过相关的仿真与实地测试,验证了测距补偿算法在测距精度上有所提高。

关键词: 测距补偿, RSSI, 补偿算法, 均值平滑

Abstract:

In view of the environmental factors that affect the traditional RSSI (Received Signal Strength Indication) ranging precision,a ranging compensation algorithm is proposed to compensate the ranging error caused by environmental factors and to handle multiple RSSI values that the same point receives by the mean value smoothing method to reduce the fluctuation of RSSI values.Simulation and field tests verify that the ranging compensation algorithm improves the ranging accuracy.

Key words: ranging compensation;RSSI;compensation algorithm;mean smoothing
