Latest Patents

One of Long Ung's latest patents is titled "Communications circuit and method with re-positionable sampling span." This invention includes a filter module with a sampling window, a control module, and an input buffer. The control module features a ray parameter interface that gathers information about significant ray changes, prompting the need to re-position the sampling window. The control module determines re-positioning parameters based on this information, which reflect the adjustments to the sampling window. The input buffer captures samples of a received signal and transmits the data to the filter module. The filter module receives the re-positioning parameters from the control module, allowing both modules to temporally adjust the sampling window in duration and/or location according to the parameters, ultimately outputting a filtered chip.

Another significant patent is "Receiver employing non-pilot reference channels for equalizing a received signal." In this invention, a receiver is equipped with a reference generator and a main equalizer. The reference generator equalizes a received signal using one or more pilot reference signals. It then decodes predetermined data channels of the equalized signal, makes hard decisions on the data, and regenerates the original coding sequence for each channel. The main equalizer utilizes each re-encoded channel as an additional reference signal, along with pilot signals, to equalize a time-delayed version of the received signal. In alternative embodiments, the receiver may also include a step-size generator that selects optimal step sizes from a look-up table based on the number of re-encoded channels and their power.
