Abstract : In spite of the advances in the state of the art of signal measurement instrumentation, the ability to recover wanted low-level signal information in the presence of inherent noise has not overcome the trend for lower and lower signal level processing. In order to recover the intelligence portion of recorded noisy signals when the wanted signals provide only a small fraction of the total signal energy involved, mathematical methods of separation and identification were investigated, and the results are presented. A model for the mathematical solution of this problem is developed and a computer program realizing the mathematical relationships is presented. (Author)
