Latest Patents

One of his latest patents is titled "Joint estimation apparatus of channel and frequency offset based on multiband-orthogonal frequency division multiplexing and thereof." This invention focuses on a joint channel and frequency offset estimation apparatus and method that utilizes a multi-band-orthogonal frequency division multiplexing system. The technology employs low-rank LMMSE channel estimation to reduce complexity while effectively joining channel estimation with frequency offset estimation. The apparatus includes a channel estimator that processes a Fourier-transformed OFDM signal and calculates channel estimation results using Linear Minimum Mean Square Error (LMMSE) techniques. Additionally, an autocorrelation unit and a frequency offset estimator work together to enhance the accuracy of frequency offset calculations.

Another significant patent is the "Service mobility management system using XML security and the method thereof." This system is designed to manage service mobility through an extensible Markup Language (XML) electronic signature. It includes a mobility interface that halts and stores the operation of a service during transitions. The service state information is serialized and converted into XML format, which is then signed electronically. This innovation ensures secure and efficient service mobility within an Open Service Gateway initiative (OSGi) framework.
