Channel integrity detection

摘要

A computer-implemented method can include determining an amplitude for each of a plurality of input channels, corresponding to respective nodes. A measure of similarity can be computed between the input channel of each node and the input channel of its neighboring nodes. The method can also include comparing an amplitude for each node relative to other nodes to determine temporary bad channels. For each of the temporary bad channels, a measure of similarity can be computed between the input channel of each node and the input channel of its neighboring nodes. Channel integrity can then be identified based on the computed measures of similarity.

1. A non-transitory computer readable medium having instructions, the instructions comprising:
a preprocessing stage to analyze input channel data for a plurality of input channels to detect channels having an integrity that is considered one of bad or good, each of the plurality of input channels corresponding to a respective one of a plurality of nodes; a first spatial similarity measurement function to compute a measure of similarity between the input channel data for each of the plurality of nodes and a set of neighboring nodes to identify a spatial correlated set of channels having an integrity that is considered one of bad or good; an amplitude analyzer to determine a subset of channels meeting amplitude criteria; a second spatial similarity measurement function to compute, for each channel in the subset of channels meeting the amplitude criteria, a measure of similarity between the input channel data for each node and a set of neighboring nodes to identify an amplitude correlated set of channels having an integrity that is considered one of bad or good; and a combiner to store output data representing the integrity of the plurality of input channels based on the integrity of the channels detected by the preprocessing stage, the spatial correlated set of channels and the amplitude correlated set of channels.
