Abstract :
This paper provides a first structured view of using the L1-norm minimization of error when computing the parameters corresponding to spectral estimation models, discussing its interest and advantage/disadvantage balance compared with the standard L2-norm minimization procedures. Some examples illustrate this comparison.
