Patent 9237044 was granted and assigned to Altera on January, 2016 by the United States Patent and Trademark Office.
One embodiment relates to a computer-implemented method that selects one of at least three procedures to determine equalization settings jointly for a transmitter and a receiver. A first process may be used if the end-of-channel signal-to-noise ratio (SNR) is greater than an SNR threshold and the equalization capability of the transmitter is greater than the equalization capability of the receiver. A second process may be used if the end-of-channel SNR is greater than the SNR threshold and the equalization capability of the transmitter is less than the equalization capability of the receiver. A third process may be used if the end-of-channel SNR is less than the SNR threshold. Other embodiments and features are also disclosed.
