Convergence behavior of a PS-FSE in the presence of a cyclostationary crosstalk interference

The convergence and steady-state behavior of a phase-splitting fractionally spaced equalizer (PS-FSE) are analyzed in the presence of a cyclostationary crosstalk interference. It is shown that the FSE in the presence of cyclostationary crosstalk has a different eigenstructure compared to the one in the presence of stationary noise. We also show that the convergence characteristic of the PS-FSE varies depending on the relative clock phase between the signal and the crosstalk.
