Description
Summary:The paper faces the problem of designing a compact processor devoted to the evaluation of a time-frequency transformation for space applications. The guidelines to save circuitry and power consumption are searched. Starting from the simple Gabor transformation, the effects of the Weyl-Heisenberg indetermination principle are examined in connection with the effects induced by the use of a short wordlength. A simple criterion to choose the optimal wavelet is given and applied to improve the transformations performed using a reduced wordlength.
