Latest Patents
One of Joong-soo Ma's latest patents is an "Apparatus and method for network-coding." This invention provides a network-coding apparatus and method that can increase data communication capacity in environments where error-correction codes (ECC) are applied. The apparatus includes a received signal processing unit that receives and decodes at least two signals, and a transmission signal processing unit that merges these decoded signals to generate a merged transmission signal.
Another notable patent is the "Method and apparatus for fine frequency synchronization in wireless broadband (WiBro) system without using global positioning system (GPS) receiver." This method measures the spread degree of a received signal of an adjacent subcarrier using the orthogonality of PN sequences to estimate frequency offsets in a base station or wireless repeater without relying on GPS. The method involves performing despreading on received adjacent subcarrier sequences, obtaining ratios of correlative values, and estimating frequency offsets based on these ratios.
