Latest Patents

One of his latest patents is titled "Apparatus and method for detecting pilot signal in mobile communication system." This invention provides a method to reduce the processing time required to demodulate a traffic channel based on channel estimation results. The apparatus includes a first channel estimator for estimating the noise component of a pilot symbol received by a first receiver, and a second channel estimator that combines pilot symbols from two receivers to improve channel estimation. An energy detector is also included to assess the energy value of the pilot symbol, which aids in determining the presence of a secondary or auxiliary pilot signal.

Another significant patent is "Apparatus and method for detecting traffic channel signal transmission in a rake receiver." This invention ensures stable and accurate detection performance for continuous and discontinuous transmission detection of traffic channels in a mobile communication system based on CDMA 2000 standards. The method compensates traffic channel signals according to fingers, combines these signals, and estimates signal-to-noise ratios to detect transmission status effectively.
