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。

By means of proposing a priori Markovian transition probability used in the model predictive probability in input synthesize, the IMM estimation algorithm not only utilizes the sufficiency system's posteriori information, but also utilizes rationally the system's priori information, which enhances estimation performance highly Theoretical analysis and simulation show the IMM algorithm is one of the most cost-effective schemes in all generalized pseudo Bayesian algorithms.

IMM估计方法通过在用于输入综合的模型预测概率中引入一个马尔可夫先验转移概率，使得IMM估计不但充分地利用了系统的后验信息，而且合理地利用了系统的先验信息，从而大大地提高了估计的精度和性能。理论分析和仿真结果表明：IMM估计方法是各种广义伪贝叶斯算法中性能最优的一种自适应估计算法。

Knowledge we gain from experience is a posteriori, and what we can know independent of experience is a priori.

我们获得的知识是从经验事后，和我们所能知道的经验，是独立的先验。

But they argue that even with a posteriori necessities, the justification for the claim of necessity must be grounded in conceptual analysis.

但是她们认为即使是后天必然的，对这个必然主张的辩护必须基于概念分析。

Knowledge of this kind is called a priori , in contradistinction to empirical knowledge, which has its sources a posteriori , that is, in experience.

我们称这种知识为"先验"。与之相对应的概念是"经验知识"——后验

In the new algorithm, SCA provides global convergence by moving the equalizer weight vector in the correct direction. After the equalizer enters the local convergence region, SDD can decrease the residual inter-symbol interference and accelerate convergence speed by maximizing the posteriori probability of the equalizer output.

该算法一方面使用了SCA算法来提供全局收敛，保证在整个收敛过程中，均衡器朝正确的方向收敛；另一方面当均衡器进入到局部收敛区域时，并行增加的SDD部分通过最大化均衡器输出的局部后验概率来降低剩余码间干扰和提高收敛速度。
