Results of the AAR indicator for test signal “1.” Five different SNRs in use are indicated by the subscripts. The box plot shows the distribution of the AAR under 100 realizations of random noise. In terms of the AAR distribution, random bases R and the orthonormalized bases O perform better than the other two systems. Normalization of the B bases resulted in a slight decrease of the AAR variance
