Latest Patents

One of his latest patents is titled "Method and apparatus for compensating for variable symbol timing using cyclic prefix in non-synchronized OFDM system." This invention discloses a method and apparatus for estimating symbol timing in a non-synchronized OFDM system. The invention includes synchronizing a frame of a received signal, estimating the symbol timing of each symbol based on the synchronization, and compensating for the symbol timing using a phase difference attributable to a Symbol Timing Offset (STO). This compensation varies within a Cyclic Prefix (CP) interval due to the frequency offset of a sampling clock and thermal noise, ultimately performing channel equalization using a preamble based on the corrected phase rotation.

Another notable patent is "Method and apparatus for inserting broadcast program by detecting available channel over hybrid fiber coax network or optical cable network." This invention involves an apparatus for combining a broadcasting channel, which includes a channel detector to identify a vacant Radio Frequency (RF) broadcasting channel. The system utilizes a photoelectric converter to convert a first broadcast program into an optical signal and subsequently into a first RF signal. It also features a broadcast receiving interface to receive at least one second broadcast program, a broadcast modulator to generate a second RF signal by modulating the second broadcast program, and a channel combiner to merge the broadcasting channels.
