Every cluster has its own signal template that differs in the signal supports.
In this example, an unrecognized signal pattern of a selected PC adopts eight faulty statuses signal templates for that PC as supervisory signals and applies PC1DARMF algorithm to find its best matching signal template.
It is also noted that for some real-time applications, signal template sets provided by only one or two PCs is recommended to reduce computational cost.
This correlation output can provide significantly higher peak gain due to the use of the virtually extended signal template which consists of the original template and a "dirty template" from data detection results.
The conventional approach, which is based on the cross-correlation between the received signal and the local signal template, is widely used in communications as well as positioning systems.
If one signal pattern and its best matching signal template turn out to both derive from the same fault type, it is regarded as correct fault diagnosis, otherwise the incorrect diagnosis.
In Table 9 statistics suggest that supervision of signal template sets of every PC results in at least one 0 correct classification rate, while the fusion gives more comprehensive results.
Specifically, in each ensemble run, six non-zero elements in each signal template are selected randomly and set to zero elements, while at the same time, six elements that are zeros in the original template are reset to be non-zeros.
aIn data communication systems, the signal template can be a training sequence which is originally designed for multiple access, synchronization or channel estimation purposes.bIn[24], the authors demonstrated the error probability of the direct path detection is a monotonously decreasing function of the SINR.
In other words, it reflects the frequencies of ascending orders of index FI n (introduced in Figure 4) in overall FI values when choosing the right signal template of PC i. P(w j |PC i ) can be calculated on the basis of statistics of extra training data set, which contains 10 simulation runs for each type with fault introduced time of the 8th h after the simulation started.
