Device and method for eye diagram generation

A receiver device, comprising:

• processing circuitry configured to:
• obtain a digital signal, wherein the digital signal is based on a transmitting signal sent by a transmitter device over a channel to the receiver device;
• sample the obtained digital signal to obtain a set of sampled digital signals;
• process each sampled digital signal of the set of sampled digital signals, based on a soft-output maximum likelihood sequence estimation (MLSE) algorithm and one or more digital signal processing (DSP) parameters, to obtain a set of processed sampled digital signals;
• reconstruct a signal histogram for each processed sampled digital signal to obtain a set of reconstructed signal histograms;
• and
• generate an eye diagram based on the set of reconstructed signal histograms.

A method for generating an eye diagram of a digital signal at a receiver device, the method comprising:

• obtaining the digital signal, wherein the digital signal is based on a transmitting signal sent by a transmitter device over a channel to the receiver device;
• sampling the obtained digital signal to obtain a set of sampled digital signals;
• processing each sampled digital signal of the set of sampled digital signals based on a soft-output maximum likelihood sequence estimation, MLSE, algorithm, and one or more digital signal processing, DSP, parameters, to obtain a set of processed sampled digital signals;
• reconstructing a signal histogram for each processed sampled digital signal, to obtain a set of reconstructed signal histograms;
• and
• generating an eye diagram based on the set of reconstructed signal histograms.
