This algorithm can achieve the best demodulation because the likelihood ratio of information is used adequately. 由于该算法充分利用了软译码得到的似然比(LR)信息,因此可以实现最优信号检测。
Generalized maximum likelihood ratio detection algorithm ( GLR ) is a typical method of space-time adaptive signal processing. 狭义最大似然比(LR)检测算法(GLR)非空时自逆当信号处放的比拟典型的算法。
Objective : To explore mathematical relation of sensitivity and specificity, likelihood ratio, predictive value in diagnostic test. 目的:探索诊断试验的灵敏度与特异度、似然比(LR)、预测值的变化关系。
It is proved by theoretical derivation that under the N-P criterion, the system fusion rules and the sensor decision rules are still the likelihood ratio threshold decision rules. 通过理论推导,证明了在N-P准则下,融合系统的融合规则和传感器的判决规则是似然比(LR)门限判决。
Based on the characteristics of the detection likelihood ratio sequence and the recursive relations, a fast algorithm is proposed. 文中根据检测似然比(LR)序列的特点,利用递推关系,提出了一种快速算法。
