Latest Patents
One of his latest patents is titled "Apparatus and method for detecting signal based on QR-decomposition in multiple input multiple output wireless communication system." This invention provides an apparatus and method for detecting multiple transmit signals in a MIMO wireless communication system. The apparatus includes an RF processor, a channel estimator, and a signal detector, which work together to convert received signals into baseband signals and estimate channel information. The signal detector then arranges these signals based on the channel information to detect the transmit signal vector.
Another significant patent is "Detection complexity reducing apparatus and method in multiple input multiple output (MIMO) antenna system." This invention aims to lower the tree searching complexity in a Spatial Multiplexing MIMO antenna system. It includes a transmitting apparatus that generates multiple transmit streams and determines modulation schemes for these streams. The receiver then detects the signals by allocating the modulation scheme of the lowest order to the upper tree level, enhancing efficiency in signal detection.
