In this algorithm, the direction-of-arrival is assumed to be a discrete random variable with a priori probability density function defined on a set of candidate points. Whether or not the secondary sample is required is based on the a posteriori probability distribution of a set of candidate point"s, which can be calculated from the array received signals. And then, the resulting beamformer is a weighted sum of the beamformers pointed at the latest set of point"s, which are combined according to the value of the a posteriori probability for each pointing direction.
在该算法中,期望信号的波达方向被看作是一个定义在若干候选波达方向上的离散随机变量,由阵列接收信号计算出各候选波达方向的后验概率,并将后验概率的分布作为是否需要进行二次采样的判断标准;随后,对各波达方向上的波束成形权值线性加权,便可得到自适应波束成形器,权系数为各候选波达方向的后验概率值。

As the mine accidents happen frequently in recent years, the detecting technology for microseism becomes much more important. However, there is no advanced microseism detecting system at home. It's pretty important for microseisms denoising and Reversion. A wavelet denoising method is presented here to process microseism signal, and the microseism record can get high signal to noise ratio. Meanwhile based on the software of LabVIEW, s design of real-time detecting system for microseism based on virtual instrument is presented. The advantage of the virtual instrument was sufficiently exerted to achieve the real-time detecting and analyzing of the microseism.

Some methods aiming at the two problems have been researched. First, the optimal number of ATE site can be calculated based on a cost model of DAT-ATE. Second, the problem of test schedule which is equitant with two-dimensional Bin-Packing problem is presented. Then a TCG denotation satisfied with T-admissible rule is more convenient for combinational optimization. With Simulated annealing algorithm, better test scheduling results can be achieved; but there is no great optimization space because the efficiency of scheduling is greater than 90%. Third, A novel test compression method——Multi-capture testing is proposed to compress the stimuli. And the ATPG results show that MC achieves high compression ratio which is greater than 90% in some large-scale circuits. MISR, widely used in LBIST, is employed to compress the responses. The aliasing analysis demonstrates that the fault coverage reduction is little due to the existence of aliasing. Fourth, an improved TIC (called S-TIC) aiming at structured test is proposed based on ARM's TIC. A MC scheduling algorithm is proposed to compute the SoC test time and combine MC vectors to SoC test vectors. The scheduling results shows that test time is greatly reduced when using the proper scheduling priority.
