Claim:
1. A communication system comprising: a control module being configured to generate a first control signal for adjusting an α parameter and a second signal for adjusting a β parameter, the α parameter and the β parameter being determined based on eye-modulation characteristics; a PAM transmitter being configured to perform eye-modulation on a source data and generate an output waveform using the α parameter and the β parameter, the α parameter being used to adjust a middle eye-height, the β parameter being used to adjust a top eye-height and a bottom eye-height, the source data comprising MSB data and LSB data, the top eye-height separating a first eye level and a second eye level, the middle eye-height separating the second eye level and a third eye level, and the bottom eye-height separating the third eye level and a fourth eye level; and a correction module being configured to measure eye-modulation characteristics, the eye-modulation characteristics including distortion and signal-to-noise ratios.
