摘要： A method for rate adaptation with extended MCS set for wideband eigen-beamforming transmission. A signaling method over multiple channels in a wireless telecommunication system including a transmitter and a receiver, performs the steps of obtaining an information bit stream, selecting the number of transmission streams, selecting different transmission rates for each MIMO OFDM transmission, and transmitting the information bit stream from the transmitter via said multiple channels over a plurality of transmitter antennas to the receiver according to the selected transmission rate per channel. Selecting transmission rates further includes the steps of selecting the transmission rates based on the diversity order of each stream. The method selects different transmission modes for each MIMO OFDM transmission and provides a simple, fast and efficient scheme to select the transmission rate for each eigen-mode transmission.

摘要： A telecommunication MIMO receiver implements soft bit metric calculation with direct matrix inversion MIMO detection. The receiver has a detector that detects data symbols in a received signal by determining distances between received signal points and constellation points; a scaler that scales the distances using a scaling factor; and a soft bit metric calculator that uses the scaled distances to calculate scaled soft bit metrics. The receiver can also have a decoder that decodes the soft bit metrics to determine data values in the received signals. Preferably, the receiver also has a quantizer that dynamically quantizes the soft bit metrics before decoding by the decoder.

摘要： A method and system for device discovery in a wireless network is provided. The device discovery involves directionally transmitting a data unit from a transmitting station over a channel in different directions to emulate omni-directional transmission, receiving the data unit transmissions from different directions at a receiving station, determining the quality of the transmissions received from the different directions, and detecting location information for the transmitting station relative to the receiving station based on the highest quality transmission among the transmissions received from the different directions. Further, if a channel has sufficient bandwidth to satisfy direct link communication between two stations, then during a direct link set-up stage, the two stations conduct a probing message exchange using omni-direction transmission, and upon successful probing, obtain communication link status information and set proper communication configurations for the two stations based on the communication link status information.

摘要： A method and system for transmission of video information is provided. A transmitting wireless station performs chroma partitioning of pixels in a video frame into different partitions. The chroma partitioning includes separating luminance (Y) information from chrominance information (CB and CR) of each pixel in a set of spatially correlated pixels. The luminance (Y) information are placed into different partitions. The different partitions into different packets and transmitted over a wireless communication medium to a receiving wireless station.

摘要： A method and system for transmitting uncompressed video over a wireless channel by inputting a frame of pixel information, partitioning spatially correlated pixels into different packets, and transmitting the packets separately over a wireless channel. For robust transmission, error detection data can be generated for each packet and appended to each packet before transmission. A receiver receives the transmitted packets and checks if a received packet is corrupt based on the appended error detection data. For a corrupt packet, the receiver corrects the corrupt pixels using pixel information in other received packets containing neighboring pixels to recover each corrupt pixel in the corrupt packet.
