Latest Patents

One of Jin Ji's latest patents is titled "Receiver signal dynamic range compensation based on received signal strength indicator." This patent discloses a method for processing a received signal at a mobile receiver in a wireless communications system. The method involves demodulating the received signal to obtain an analog baseband signal, which is then converted into a digital baseband signal. The signal strength of the digital baseband signal is estimated, and using this estimation, the signal is scaled by a scaling factor. The digital baseband signal is subsequently equalized into an equalized digital signal, which is then rescaled by a resealing factor.

Another significant patent is "4×4 pixel-based edge detection and edge enhancement without line buffer overhead." This innovation enhances the visual quality of enlarged images by detecting diagonal edges and applying a suitable scaling algorithm, such as a rotated bilinear scaling process. The process involves detecting diagonal edges, specifying a new frame of reference rotated 45 degrees from the original, and selecting a rotated pixel set based on this new frame. Bilinear interpolation in the new frame of reference using the rotated pixel set provides improved pixel data for the output pixel, while standard bilinear interpolation is used for pixels not associated with diagonal edges.
