摘要：In order to realize accurate tracking task with wireless sensor network, a signal character sequence particle filter algorithm is proposed which is generic and compatible with different physical layers. The signal character sequences are used to translate the signal from the physical layer to the abstract layer and realize the update of the particle weights. To overcome the degeneration and impoverishment problems of the classical particle filter algorithm, trace prediction, cross operation and resample method are proposed to sample particles from the posterior distribution. In addition to the basic algorithm, multidimensional filtering is also adopted to deal with the noise. Simulation results show the effectiveness of the improvement measures of the algorithm.
