  The novel approach was developed for multilevel signal detection in channels
with impulsive non-Gaussian noise. This approach consists of using
morphological nonlinear image filtration principles for two dimensional
signals. It is a new method of signal demodulation, using three - dimensional
image processing algorithms. Successful results of this morphological detector
encourage more investigation towards using image processing theory and
algorithms for two dimensional signal processing. As can be seen in the example
in section IV, this new approach of reusing well developed and extensively
developing image processing has significantly improved performance.
