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。

We will demonstrate the specification of reference prior distribution on the random covariance matrix. We will consider the approximate uniform shrinkage prior and approximate Jeffreys' prior. Both are formulated based on the approximated likelihood function. Under generalized linear mixed models, we show that the posterior mode under Jeffrey's prior is asymptotically closer to the REML estimate than the mode under uniform shrinkage prior does.

parity bit:校验位
校核数据完整性的一种方法,一个字节的8个数据位与校验位(parity bit)加起来之和有奇数个1. 校验线路在收到数后,通过发生器在校验位填上0或1,以保证和是奇数个1. 因此,校验位是0时,数据位中应该有奇数个1;而校验位是1时,数据位应该有偶数个1.

Posterior distribution:后验分布
参数被看成是随机变量,它的概率分布有两种:第一种是在试验之前就已经知道的被称为先验分布(prior distribution),它可以通过对以往的关于参数的知识进行总结作一个主观判断得到;第二种是在试验之后得到的被称为后验分布(posterior distribution).

a posteriori:后验
在知识论上,到底数学真理是先验(a priori)、后验(a posteriori)、还是约定俗成(conventionism)的呢?如果是先验,为什麽能够应用在物理界内、能跟偶存、随机的感官世界相吻合呢?另外,既然放诸四海皆准,为何其内部会有如Burali-forti或罗素所提出的悖论的产生呢?
