Latest Patents

Among Lee's latest patents is the one detailing "Apparatuses and methods for joint interference cancelation". This invention involves a sophisticated communication circuit arrangement designed to enhance signal clarity. It incorporates a first kernel dimension filter circuit to estimate an interference signal from a first amplifier, alongside a second kernel dimension filter circuit for a second amplifier. The arrangement utilizes a joint delay tap dimension filter to create an estimated joint interference signal, which is then removed from the received signal by a cancelation circuit, resulting in a clean output.

Another notable patent is the "Methods and devices for self-interference cancelation". This invention features a communication circuit that applies both kernel dimension and delay tap dimension filters to an input signal to generate an estimated interference signal. The cancelation circuit plays a crucial role in subtracting this estimated signal from the received data, thereby enhancing the overall signal quality. The filter update circuit ensures the filters are optimally adjusted using the clean signal.
