Residual ISI Obtained by Blind Adaptive Equalizers and Fractional Noise

Figure 17

Histogram of the Hurst exponent (belonging to the ISI) for different step-size values by using Godard’s algorithm, a 16QAM source input going through Channel 2, and a 13-tap-length equalizer. 𝑁≃9000 and 𝑛_𝑝=[100200300400]. The upper, bottom left, and bottom right figures were obtained for 𝜇=0.00001, 𝜇=0.00003, and 𝜇=0.00009, respectively.
