PCT No. PCT/GB97/00453 Sec. 371 Date Dec. 1, 1998 Sec. 102(e) Date Dec. 1, 1998 PCT Filed Feb. 19, 1997 PCT Pub. No. WO97/31368 PCT Pub. Date Aug. 28, 1997A signal processing arrangement for discriminating a time varying band-limited input signal from other signals using time encoded signals. A received input signal is encoded as a time encoded signal symbol stream from which a fixed size matrix is derived. A plurality of archetype matrices corresponding to a plurality of different input signals are stored, each having been generated by encoding a corresponding input signal into a respective time encoded signal stream from which a respective archetype matrix is derived. A plurality of features are selected and excluded from the archetype matrices to generate corresponding archetype exclusion matrices. An input signal exclusion matrix is generated from the input signal matrix and each of the archetype exclusion matrices. The input signal exclusion matrix is compared with each of the archetype exclusion matrices to generate an output identifying the input signal. |
