摘要： A movable portion of an array of antenna elements receives RF signals. A movable ultra-wideband (UWB) transmitter is connected to each antenna element, via a RF to UWB converter. A fixed portion of the antenna array is separated from the movable portion by an air gap. The fixed portion includes one fixed UWB receiver for each movable UWB transmitter. An application system is connected to the fixed UWB receivers. The UWB signals from the movable transmitter are sent across the air gap to the fixed UWB receivers to be processed by the application system as the movable portion rotates.

摘要： A method communicates symbols in a cell of a multiple-input multiple-output (MIMO) network that includes a set of mobile station and a base station. The symbols are communicated using orthogonal frequency division multiplexing (OFDM) and time division duplex (TDM). A frame for communicating the symbols between the base station and the mobile station is constructed. The frame is partitioned into a downlink subframe and an uplink subframe. The uplink subframe is partitioned into a first zone and a second zone, wherein the first zone uses orthogonal frequency division multiple access (OFDMA) and the second zone uses single carrier frequency division multiple access (SC-FDMA).

摘要： The embodiments of the invention provide an adaptive method for base station cooperation in a wireless network. In a multi-user communications network that includes base stations, and in which each base station is associated with a cell, and in which each cell includes one or more mobile stations, each base station determines pre-coding matrices for full-cooperation, semi-cooperation and non-cooperation. Each base stations also determines a sum rate SRfull for full-cooperation, a sum rate SRsemi semi-cooperation, and a sum rate SRnon for non-cooperation. Then, each base station selects the pre-coding for full-cooperation, the pre-coding matrices for semi cooperation, or the pre-coding matrices for non cooperation. Each base station transmits signals according to the selected per-coding matrices.

摘要： A method for selecting antennas in a multiple-input, multiple-output wireless communications network that includes multiple stations is presented. Each station includes a set of transmit RF chains and a set of receive RF chains, and each RF chain is connectable to a set of antennas. A first station transmits a training frame for each possible subset of the set of antennas, and the set of transmit RF chains are connected to the subset of antennas according to a connection mapping rule while transmitting each training frame. A subchannel matrix is estimated in a second station for each frame. The subchannel matrices are combined to obtain a complete channel matrix. A particular subset of the antennas is selected according to the complete channel matrix. The set of transmit RF chains is connected to the selected particular subset of antennas to transmit data from the first station to the second station.
