Latest Patents
Among his recent contributions to the field are two groundbreaking patents. The first patent, titled "Decision feed forward equalization for partial response equalized signal including pre-cursor cancelation," describes a receiver comprising a decision feed forward equalization (DFFE) system. This system generates a detected signal based on a digital signal that includes intersymbol interference (ISI) values introduced by communication channels. The DFFE system effectively cancels these ISI values from the detected signal to deliver a compensated signal and set of compensated symbol values.
The second patent, "Decision feed forward equalization for intersymbol interference cancelation," outlines a DFFE system integrated into a partial response system. This innovative approach addresses both pre-cursor and post-cursor ISI by processing detected signals to yield estimated transmitted symbol values, which are subsequently used to cancel the interference and produce a compensated output.
