摘要
Systems, device, and methods related to estimating a Signal to Noise Ratio (SNR) of a signal are disclosed. A method of estimating an SNR includes setting a threshold of a comparator of a physical layer device to a first value, applying a signal to the comparator, and determining a first bit error number of an output of the comparator with the threshold set at the first value. The method also includes setting the threshold of the comparator to a second value that is different from the first value, applying the signal to the comparator, and determining a second bit error number of the output of the comparator with the threshold set at the second value. The method further includes determining an SNR of the signal based on the first bit error number and the second bit error number.
