Abstract :
This paper describes a method using a subspace algorithm that can be used to discriminate between signals. Discrimination is necessary to ensure that the same transient from different data records is used in processing. The subspace discrimination algorithm was tested against synthetic transients and found to discriminate well at high signal-to-noise ratios (SNRs).
