Residual ISI Obtained by Blind Adaptive Equalizers and Fractional Noise

Figure 16

Hurst exponent results (belonging to the ISI) for different SNR values (the added noise was a white Gaussian process (𝐻=0.5)) by using Godard’s algorithm, a 16QAM source input going through Channel 2, step-size parameter 𝜇=0.00001, and with a 13-tap-length equalizer. 𝑁≃9000 and 𝑛_𝑝=[100200300400].
