Latest Patents
One of Eilers' latest patents is the "ATV television system with reduced co-channel NTSC interference." This innovative system minimizes co-channel interference into NTSC receivers from digitally transmitted ATV signals. It utilizes the NTSC receiver's subjective random noise sensitivity characteristic to shape the ATV transmitter power curve. A complementary filter is incorporated in ATV receivers to compensate for the shaped ATV transmitter power curve, emphasizing signals at frequencies where the NTSC subjective random noise sensitivity is low.
Another significant patent is the "Co-channel interference reduction system for digital high definition." This system includes a transmitter with a modulo 4 processing precode filter. The receiver features selectable video processing modes, with the first mode providing a comb filter to remove co-channel interference signals. In the alternate mode, a level slicer and postcoder restore the precoded signal to the original four-level data signal in the absence of co-channel interfering signals.
