Latest Patents
Among his latest patents, one notable invention is the "Device and method for on-line adaptive selection of baud rate." This innovation utilizes an on-line probing technique to determine the optimal baud rate and carrier frequency for data transmission using a modem on a communication channel. The technique leverages information from a decoder noise power spectrum, estimated from equalized received modulated signals and decoder output symbols, to ascertain decoder signal-to-noise ratios (SNRs) and supported bit rates. These SNRs and bit rates, along with a band edge SNR difference at each frequency band, are utilized to select the optimal baud rate and carrier frequency.
Another significant patent is the "Device and method for automatically adjusting a phase-locked loop." This invention features a self-adjusting phase-locked loop (PLL) parameter adjusting device that automatically adjusts the PLL to provide tracking ability as needed. The method involves integrating the PLL error output signal over multiple samples, checking a predetermined number of sums, and automatically adjusting PLL parameters based on a predetermined strategy.
