Title: Innovations of Jung Joo Lee
Introduction
Jung Joo Lee is a prominent inventor based in Sunnyvale, CA. He has made significant contributions to the field of communication systems, particularly in the area of digital signal processing. With a total of 3 patents to his name, Lee continues to push the boundaries of technology.
Latest Patents
One of his latest patents focuses on energy-efficient phase shifting in digital beamforming circuits for phased array antennas. This technology is directed towards enhancing energy efficiency in communication systems. The digital signal processing circuitry includes a first phase shifter that generates second data by phase shifting first data according to a rotation-based operation without multiplication of the second data. Additionally, a second phase shifter generates fourth data by phase shifting third data according to the same operation. A combiner then generates fifth data by adding the second and fourth data, while a multiplier produces sixth data by multiplying the fifth data by a constant value.
Another notable patent involves packets with header replicas for contention resolution in communications systems. This technique aims to improve the packet error rate associated with processing packets. In this system, a first packet is received in a first slot of a frame, along with a second packet in a second slot. The first packet contains a first header and a replica of that header, indicating its association with the second packet. The system generates a second header based on the first header and the replica, which indicates an association with the second packet. A third packet is then created that includes the second header, facilitating a contention resolution process on packets associated with the frame's slots.
