Title: Byungwook Cho: Innovator in Channel Equalization Technologies
Introduction
Byungwook Cho is a notable inventor based in Hwaseong-si, South Korea. He has made significant contributions to the field of channel equalization, holding a total of 5 patents. His work focuses on improving data transmission and error detection in communication systems.
Latest Patents
Cho's latest patents include an "Apparatus and method for channel equalization based on error detection." This invention features an equalization circuit, an error prediction circuit, a sequence estimation circuit, and a selection circuit. The equalization circuit generates a first data sequence and a first equalized signal from an input signal received through a channel. The error prediction circuit predicts errors based on the first equalized signal. When an error is predicted, the sequence estimation circuit generates a second data sequence from the first data sequence and the predicted error. The selection circuit outputs the second data sequence when the predicted error is confirmed as an actual error, otherwise outputting the first data sequence.
Another significant patent is the "Eye opening measurement circuit calculating difference between sigma levels, receiver including the same, and method for measuring eye opening." This invention includes a receiver with a sampler that samples voltage levels corresponding to logical values of data based on a sampling clock. An equalizer adjusts these voltage levels, while a clock and data recovery circuit recovers the sampling clock. The eye opening measurement circuit tracks sigma levels and calculates the difference between them, enhancing the accuracy of data transmission.
