Patent number: 9948435Abstract: Method and system for providing seamless match point switching in an adaptive decoder (e.g., an MLSE decoder) that is based on estimation of symbol sequences, according to which statistics regarding samples corresponding to different symbol sequences in alternative match points are collected by a statistics collector, to create a set of figures of merit representing the quality of each alternative match point, while different match points are obtained by changing the delay of symbols decoded by the adaptive decoder and samples entering the statistics collector. A figure of merit of the current match point is compared to the figure of merit of alternative match points. Whenever an alternative match point figure of merit is better than the current match point by a predefined threshold, a decision to switch to the alternative match point is made.Type: GrantFiled: July 19, 2016Date of Patent: April 17, 2018Assignee: MULTIPHY LTD.Inventors: Omri Levy, Hanan Leizerovich, Yaron Bebes, Nir Sheffi

Patent number: 9755791Abstract: Method and system for estimating an eye diagram display of a real signal passing through a data communication channel, according to which decoded symbols of the transmitted real signal are captured, along with their corresponding ADC sample values and sampled at a rate of 1 SPS or more. Then statistic data is collected for each captured sequence of bits/symbols for each particular phase and a synthetic signal is created, based on the collected statistics, using a signal generator that produces samples by randomly creating a bit stream by generating a corresponding one or more samples for any symbol sequences in the bit stream according to the number of collected phases. Interpolation on the corresponding samples is then performed, according to required display time resolution and the synthetic signal is then displayed as a two-dimensional eye diagram image, representing all the statistics collected at all phases.Type: GrantFiled: July 14, 2016Date of Patent: September 5, 2017Assignee: MULTIPHY LTD.Inventor: Hanan Leizerovich
