With a total of 2 patents to his name, Kuo's work has advanced the capabilities of digital broadcasting systems.

Latest Patents

Kuo's latest patents include a Viterbi decoding apparatus and method. This innovative apparatus consists of a main decoder, a re-encoder, an adjusting module, a secondary decoder, and a secondary result generating module. The main decoder executes a Viterbi decoding process on input data, producing a set of main decoded results. The re-encoder then performs a convolutional encoding process on these results, leading to the generation of re-encoded results. The adjusting module modifies the input data based on these results, creating adjusted input data that corresponds to a predetermined path in a Viterbi trellis diagram. The secondary decoder generates multiple symbols from the adjusted input data, while the secondary result generating module produces a set of secondary decoded results based on these symbols and the main decoded results.

Another significant patent is for a digital broadcasting receiving system and its associated signal processing method. This system includes a receiving module that captures multiple symbols, each carrying subcarriers of a control signal. A converting module performs FFT on respective subcarriers to generate converted values. The demodulating module then executes differential demodulation on these values, leading to the generation of demodulation values. Finally, a combining module soft-combines these values to produce a prediction value corresponding to the symbol, while a determining module identifies synchronization segments in the control signal.
