查询词典 probability density function

In the monitoring, the observed behaviour of process is analyzed to infer the probability that Markov chain model of normal profile supports the observed behaviour. A low probability of support indicates a anomalous process behavior that may result from intrusive activities.

监视过程中，根据马尔可夫模型对所观察到的进程行为的分析和概率推断来判定其行为是否偏离正常的行为轮廓，较低的概率意味者该行为是由入侵活动所引起的异常行为。

Aim To discuss and analyze the formation of normal probability curve and the features of De Moivre's probability thought.

The Generalized Kolmogorov Probability generalized the 1st Kolmogorov's axiom and allows the probability values to be within the whole open real interval of (-infinite,+infinite).

广义的柯尔莫果洛夫概率(Generalized Kolmogorov Probability)推广了柯尔莫果洛夫概率三公理的第一公理：概率可在开区间范围内取值。

No additional data for frequency tracking are need, but higher estimation accuracy and low computational complexity can be obtained. Finally, a kind of optimizing joint algorithm for symbol timing, frequency synchronization and channel estimation is proposed. The false alarm probability and miss detect probability of the symbol timing are derived. We proved that the time－frequency offset domain random sequence sliding in the frequency offset direction is orthogonal with the original random sequence, and proposed a new integer frequency offset estimation algorithm. The coarse estimation methods for fractional frequency offset both in AWGN and multipath channels are proposed too.
