为了解决无线网络信号在传输过程中由于受到其他信号的干扰,导致接收端接收的信号与原始信号相比存在误差的问题,本文在利用数据关联和卡尔曼滤波对信号进行融合的基础上,提出了一种新的信号状态融合方法( signal fusion based on wavelet transform and date association,SFTD),该方法利用FARIMA( p,d,q)模型和数据关联来建立一种新的信号融合算法。通过仿真实验研究了信号发送速率与干扰信号功率之间的关系,仿真结果说明,SFTD算法比FSWC算法具有更好的信号状态融合准确性；并且发送速率、功率对融合信号也产生较大影响。

In order to solve the existed problem of error that the wireless network signal in the transmission process inter-fered by other signals, results in signal received by a receiving terminal compared with the original signal, and based on u-sing the data association and Calman filter to realize signal fusion, the paper puts forward a new fusion method for signal state ( signal fusion based on wavelet transform and date Association, SFTD) , which adopts FARIMA ( p, d, q) model and data association to establish a new fusion algorithm of signal. Through the simulation research of the relationship between the signal transmission rate and the interfering signal power, the simulation results show that aimed at the signal state fusion accuracy, the SFTD algorithm is better than FSWC algorithm; simultaneously, a transmission rate and power also have a great impact on the signal fusion.
