Latest Patents

One of Yu Wang's latest patents is titled "System and method to optimize multicarrier communication." This invention provides a system and method for allocating transmitter power to subcarriers of a multicarrier signal. Initially, subcarriers are transmitted with an initial set of power levels and constellation assignments. Quantized SNR metric values are then measured at the receiver for each subcarrier. The measured subcarrier quantized SNR metric is compared with the respective allocated constellation quantized SNR metric to determine the excess SNR per subcarrier. The transmitter power of subcarriers with excess SNR above a predetermined threshold is adjusted while keeping the total transmitter power constant. This adjustment can enhance throughput or system robustness. For increased accuracy, several training frames may be utilized, and only equally spaced constellations, such as square or cross constellations, are employed. A preferred embodiment involves using IFFT prescalers in the transmitter power adjustment for OFDM/DMT multicarrier systems.

Another significant patent by Yu Wang is the "Packet-switched network synchronization system and method." This synchronization system is designed for use in a packet-switched communication network. It comprises a transmitter-identification system, a packet-boundary detection system, and a storage-access system. The transmitter-identification system allows each receiving terminal within the network to recognize the identity of the originating transmitter terminal for a given packet of information before its reception. The packet-boundary detection system enables the detection of packet synchronization parameters for all transmitter-receiver pairs within the network. The storage-access system stores these parameters and allows the receiver to access them. The synchronization method involves detecting synchronization parameters, establishing the identity of the originating transmitter for an incoming packet, accessing corresponding synchronization parameters, adjusting the receiver based on these parameters, and decoding the incoming packet.
