摘要： A method and apparatus for determining stream weights is provided herein. During operation, an uplink direction of arrival (DOA) and a downlink direction of departure (DOD) calibration procedure is implemented using uplink signals and GPS information from a subset of mobiles without the need of calibration circuitry at the base. Because the presented calibration procedure needs no new hardware it can be deployed in existing deployments with only a soft-ware upgrade.

摘要： A method, apparatus and system for performing over-the-air calibration routines in a multiple-input multiple-output (MIMO) communication system. An antenna array of a transceiver (e.g., transceiver of a base station) comprises a re-configurable antenna having two switchable configuration states. The antenna exhibits different degrees of electromagnetic coupling to other antennas of the array in a first state than in a second state. The reference antenna is switched to the first state for performing uplink/downlink calibrating transmissions and switched to the second state during uplink and downlink communications or channel sounding calibrating transmissions.

摘要： A receiving device and method for operating a communication system are provided. The receiving device receives at least one Doppler channel estimate for at least one transmitter and a spatial covariance matrix of a corrupting environment. The Doppler channel estimates are used to create a Null Doppler spatial covariance matrix. A total Doppler spatial covariance matrix is created as a sum of the spatial covariance matrix of the corrupting environment, plus the Doppler spatial covariance matrix. A combining weight for at least one transmitter and at least one Doppler channel is created from the total Doppler spatial covariance and the at least one Doppler channel for the at least one transmitter.

摘要： A method used in a communication system (10) having central controllers (14) in communication with a plurality of user devices (12) where synchronizing data (34) and user data (35) are transmitted for a predetermined period of time defining a dwell (30). The method for delivering data to more than one user device (12) simultaneously includes the steps of providing an indicator (34) associated with at least a portion of a dwell indicating that the transmission of user data (35) is directed towards more than one user device (12), and informing the user devices of the repetition rate at which the indicator is transmitted. The user device schedules periods of time during which it is enabled and disabled respectively, based upon the repetition rate of the indicator received such that the user device is enabled and receives the data directed towards more than one user device.

摘要： A method and a system for calibrating at least one antenna (1,1-1,3. 1,j). At least a first antenna (1,4) within a first antenna array (102) can be selected as a primary reference antenna. At least one antenna (4,3) that is not within the first antenna array can be selected as a secondary reference antenna. At least a first signal propagation characteristic (122) can be measured based on at least one signal wirelessly communicated between the primary reference antenna and the secondary reference antenna. At least a second signal propagation characteristic (118) can be measured based on at least one signal wirelessly communicated between the secondary reference antenna and at least a second antenna (1,2) within the first antenna array. At least a first calibration coefficient can be determined for the second antenna.

摘要： The invention computes frequency-domain channel gains by compiling a set of estimated channel gains as a function of pilot sequences, a set of analytical channel gains variables, and a set of weighting coefficients variables. A plurality of weighting coefficients are computed as a function of time and frequency correlation functions, a noise correlation matrix, and pilot sequences. A weighting matrix is computed from the weighting coefficients. After receiving a training sequence from at least one transmitter, a received data matrix is computed from the training sequence. The weighting matrix and the received data matrix are used to compute the frequency-domain channel gains. The invention also provides a method for reducing the computational complexity of estimating the time and frequency response of at least one desired signal received by at least one antenna. Also, the time and frequency response of at least one desired signal received by at least one antenna can be both interpolated and predicted with the present invention.
