Eye modulation for pulse-amplitude modulation communication systems

A method for performing pulse-amplitude modulation, the method comprising:

• receiving a first data stream;
• determining one or more SNR values associated with a data path by a receiving entity;
• receiving the SNR values;
• calculating a α parameter based on the SNR values, the α parameter being associated with a middle eye height;
• calculating a β parameter based on the SNR values, the β parameter being associated with a top eye height;
• performing eye modulation on a second data stream;
• compensating eye levels of the second data stream using at least the α parameter and the β parameter;
• and
• transmitting the modulated second data stream.

A method for performing pulse-amplitude modulation, the method comprising:

• receiving a first set of SNR values associated with a first data stream from a receiving entity;
• calculating a α parameter based on the SNR values, the α parameter being associated with a middle eye height;
• calculating a β parameter based on the SNR values, the β parameter being associated with a top eye height;
• performing eye modulation on a second data stream by a transmitting entity;
• compensating eye levels of the second data stream using at least the α parameter and the β parameter;
• transmitting the modulated data stream;
• receiving the second set of SNR values associated with the second data stream the receiving entity;
• and
• adjusting the α parameter and the β parameter based on the second set of SNR values by the transmitting entity.
