Residual ISI Obtained by Blind Adaptive Equalizers and Fractional Noise

Figure 15

Hurst exponent results (belonging to the ISI) for different equalizer’s tap-length by using Godard’s algorithm, a 16QAM source input going through Channel 2, step-size parameter 𝜇=0.00001 and SNR=12 [dB] (the added noise was a white Gaussian process (𝐻=0.5)). 𝑁≃9000 and 𝑛_𝑝=[100200300400].
