In this paper the innovative time-domain pre-distortion method is proposed. This method (PWM-RC) uses raised-cosine (RC) pulse shaping and pulse-width modulation (PWM) scheme to achieve better output channel data response. The conventional pre-distortion methods based on finite impulse response (FIR) filtering are not compatible with modern low-power CMOS design. Existing perspective time-domain pre-distortion methods show many high frequency harmonic components in the pre-emphasized signal. It can cause more system crosstalk susceptibility, where the additional pre-emphasis boosted the undesirable high frequency components. The proposed method reduces the content of higher harmonic components at the pre-emphasized output signal and ISI (inter-symbol interference) effects. Advantageous properties of the PWM scheme such as high channel loss compensation are preserved. Finally, the simulation results realized in MathCAD and ADS Agilent Development Studio are introduced.
