Latest Patents

Hing “Ada” T Hung holds a patent for a technique aimed at minimizing decision feedback equalizer wordlength in the presence of a DC component. This innovative system reduces the complexity of an adaptive decision feedback equalizer. The patent describes a method where QAM and VSB symbols, expressed in two's complement notation, include an extra bit to compensate for a fixed offset term. The decision feedback equalizer operates on symbolic decisions represented by a wordlength that excludes this added bit. The vestigial word is convolved with the decision feedback filter's coefficients, while a DC component is convolved with the same coefficients in a correction filter. This process provides an ISI compensation signal at the input of a decision device, such as a slicer.
