Latest Patents

Wookwon Lee's latest patents include innovative solutions for power control in mobile communication systems. One of his patents describes a closed-loop power control apparatus implemented within a basestation. This apparatus receives a series of physical channels from a mobile station simultaneously in a DS-CDMA communication system, such as those based on the cdma2000 specifications. The power control apparatus includes a series of Rakes that separate the code-subchannels, along with SINR estimation devices that estimate the SINR for each code-subchannel. Comparators generate a multiple of power control bits based on the comparison results between the SINR estimates and a set of power threshold levels. These power control bits are transmitted to the mobile station, allowing it to control the transmit powers for the physical channels individually.

Another significant patent involves systems and methods of channel coding and inverse-multiplexing for multi-carrier CDMA systems. This invention discloses methods and apparatus for transmitting data over a multi-channel CDMA system. The system includes an encoder for encoding a data stream with error correction, an interleaver for interleaving the data stream, a multiplexor for multiplexing a plurality of power control symbols onto the data stream, and an inverse-multiplexor for inverse-multiplexing the data stream onto multiple different communication channels. Additional error correction encoding and interleaving steps may also be included.
