Each subscriber station independently transmits information to a base station that allows the base station to determine beamforming vectors for each subscriber station by ranking the subscriber stations by channel strength. Using sequential nullspace methods, the ranked channel matrices are then used to select the channel matrix Hi for the best subscriber station, to design the wi, vi for the best subscriber station as the left and right singular vectors of the MIMO channel matrix Hi, to transform the remaining channels and to continue the process until beamforming vectors are designed for all channels.

  • Patent number: 8068790
    Abstract: A method for accessing an RF begins by determining whether information is to be transmitted via the RF bus. The method continues by determining whether the RF bus is available when the information is to be transmitted via the RF bus. The method continues by securing access to the RF bus when the RF bus is available. The method continues by converting the information into RF bus signal and by transmitting the RF bus signal via the RF bus when access to the RF bus is secured.

  • Patent number: 8068872
    Abstract: A mobile phone is described herein that has control (or at least partial control) over which virtual antenna(s) in one or more base stations should be used for transmissions. In one embodiment, the mobile phone performs the following steps: (1) receives an antenna subset list (from the scheduling unit) which identifies a configuration of virtual antennas that is associated with the base station(s); (2) uses the antenna subset list to select which virtual antenna(s) in the configuration of virtual antennas should be used for transmissions; and (3) sends an antenna selection signal (to the scheduling unit) which contains information that instructs/requests the base station(s)/scheduling unit to use the selected virtual antenna(s) for transmissions.

  • Patent number: 8063712
    Abstract: Methods and systems for VCO impedance control to optimize performance, efficiency, and power consumption are disclosed and may include selectively coupling one of a plurality of taps on a multi-tap inductive load to a voltage controlled oscillator (VCO) on a chip comprising a plurality of transmitters and receivers. The multi-tap inductive load may comprise a multi-tap transformer or transmission line, which may be integrated on the chip, or may be integrated on a package to which the chip is coupled. A voltage swing at an output of the VCO and/or a current in the VCO may be adjusted by configuring a load of the VCO utilizing the multi-tap inductive load. The multi-tap inductive load may be coupled to the VCO utilizing one or more CMOS switches.

  • Patent number: 8064387
    Abstract: A wireless-linked remote ecological environment monitoring system is proposed, which is characterized by the use of a sensor network such as WSN (wireless sensor network) installed at the remote site for collecting ecological data, and the use of a public wireless communication system such as GSM (Global System for Mobile Communications) for transferring all the collected ecological data to a back-end host server unit where the ecological data are compiled into webpages for posting on a website. This feature allows the research/management personnel to browse the ecological data simply by linking a network workstation via a network system such as the Internet to the website, without having to travel to the remote site and collect ecological data by human labor.

  • Patent number: 8055218
    Abstract: This invention provides a wireless transmitter circuit for mobile communication apparatus and this circuit can be configured with fewer components and is suitable for downsizing. A single PLL synthesizer serves as both RF frequency band PLL and IF frequency band PLL among three oscillators for TX, RX and IF frequency bands, which have been required in conventional mobile communication apparatus. The number of necessary oscillators occupying a large area within a chip is reduced and the number of components is decreased. Specifically, circuitry is arranged to generate local oscillation signals for RF and IF frequency bands by frequency dividing the output of a VCO of the RF frequency band PLL.
