Latest Patents

Among his latest inventions is a "Rate matching device and method for a data communication system." This device enhances the efficiency of channel-encoded symbols within data communication systems. It operates effectively with both non-systematic codes, such as convolutional codes or linear block codes, and systematic codes like turbo codes. The rate matching device consists of multiple rate matching blocks, which correspond to the reciprocal of the coding rate of a channel encoder. This technology allows for flexible adjustment of parameters, including input and output symbols and various coding patterns.

Another significant innovation is the "Turbo interleaving apparatus and method," which introduces a 2-dimensional interleaving technique. This method involves dividing input information bits into several groups, storing them sequentially in memory, permuting the bits based on a predefined rule, and effectively shifting the last bit of the last group to a new position. This process enhances the selection of groups and information bits, contributing to improved data handling in communication systems.
