  • Publication number: 20110134775
    Abstract: Methods and apparatus are disclosed for applying successive multi-rank beamforming strategies (e.g., successive precoding strategies) for the design of precoders over a set of parallel channels. Successive beamforming is applied to a narrow band channel model and is also applied for finer quantization of a single beamforming vector (e.g., recursive beamforming). A first embodiment provides the optimal approach with high complexity. An alternative embodiment provides successive beamforming for near optimal precoding selection with medium complexity. A low complexity method for precoder selection is also provided wherein a channel representative matrix for the set of parallel channels is determined and successive beamforming on the calculated channel representative is applied.

  • Patent number: 7949318
    Abstract: A multi-rank beamforming (MRBF) scheme in which the downlink channel is estimated and an optimal precoding matrix to be used by the MRBF transmitter is determined accordingly. The optimal precoding matrix is selected from a codebook of matrices having a recursive structure which allows for efficient computation of the optimal precoding matrix and corresponding Signal to Interference and Noise Ratio (SINR). The codebook also enjoys a small storage footprint. Due to the computational efficiency and modest memory requirements, the optimal precoding determination can be made at user equipment (UE) and communicated to a transmitting base station over a limited uplink channel for implementation over the downlink channel.

  • Publication number: 20110082821
    Abstract: A method for generating precedence-preserving crossover and mutations operations for genetic algorithms is provided. The method is based on the determination of activities' Forward Free Float (FFF) and Backward Free Float (BFF) values, utilizing these float values in randomly selected forward and backward paths, respectively. The method may be applied to the finance-based scheduling domain using large scale projects, with the chromosomes of the genetic algorithm encoding activities' start times in a resource-constrained scheduling problem.

  • Patent number: 7917176
    Abstract: A quantized multi-rank beamforming scheme for multiple-antenna systems such as a multiple-input-multiple-output (MIMO) wireless downlink. User equipment (UE) estimates downlink channel and transmit power and determines rank and power allocations. A quantized beamforming matrix is then determined by the UE using successive beamforming. The UE also determines channel quality indices (CQI) which it feeds-back to the wireless downlink base station along with the index of the quantized beamforming matrix. The base station uses the CQI information to select a UE for scheduling of downlink transmission and the quantized beamforming matrix index received from the selected UE to beamform the downlink transmission to the UE. Base station overhead and is minimized while providing near-optimal performance given the constraints of a limited feed-back channel and computational complexity of the UE.

  • Publication number: 20110007757
    Abstract: A system and method for implementing a network encoding scheme includes buffering a signal in quantized form at a node of a network and permuting the signal into a particular order of code blocks. The code blocks are rotated using at least one key which has been assigned to the node, wherein the at least one assigned key is a value which is used to control the amount of rotation. The rotated code blocks are then combined to generate a combined signal. The combined signal is permuted back to generate at least one output signal.

  • Publication number: 20100265153
    Abstract: A coaxial to microstrip transition is introduced in a multi layer mixed dielectric printed circuit board environment that provides a 50 Ohm impedance system between a coaxial antenna feed and a surface mount diplexer at Ku-band frequencies. The 50 Ohm transition from the coaxial antenna feed to the diplexer at microwave frequencies lossy FR-4 style laminate is provided by constructing a PCB internal coax using the center conductor of the antenna feed and a dual ring of plated through hole VIAs. The transition from the PCB internal coax to the microstrip section of the high frequency laminate PCB layer uses a ā€œDā€-style opening in the ground layer and a VIA ring arrangement between the layers to optimize or tune the performance of the transition. Additional features in the interface construction are implemented to guaranty that its microwave and mechanical performance does not degrade in extreme environmental conditions.

  • Patent number: 7805110
    Abstract: A method is disclosed for determining whether to transmit from a first unit to a second unit, where the transmission is one of a first type and a second type. In the method, a signal from the second unit is received at the first unit, and the strength of the signal as received at the first unit is measured. A determination is made of whether the transmission is of the first type or the second type, and a first threshold is selected if the transmission is of the first type, or else a second threshold is selected if the transmission is of the second type. The measured signal strength is then compared to the selected threshold, and the transmission proceeds only if the measured signal strength exceeds the selected threshold.

  • Publication number: 20100188167
    Abstract: A compact Ku band microwave diplexer configured as a three port surface mount component on a miniature alumina substrate. Input signals occurring at a common port having frequencies within a first pass band are passed to a second port while being isolated from signals occurring at a third port. Signals occurring at the third port are passed to the common port while being isolated from the signals at the second port. A microstrip dual spur line filter is used combined with open circuit stubs to provide enhanced second harmonic suppression on the transmit side, while using a coupled line microstrip filter on the receive side. This approach allows for compact size and automated component assembly through pick and place and reflow manufacturing techniques.

  • Patent number: 7759288
    Abstract: Base treated aluminas exhibit improved CO2 capacity over untreated aluminas. Base treated aluminas prepared by physically mixing alumina and base during forming have (1) a higher surface area, (2) less hydrothermal aging, (3) improved CO2 capacity and (4) lower cost than base treated aluminas produced by aqueous impregnation. A method for removing at least CO2 and water from a gas stream includes providing an adsorbent formed from a process comprising physically mixing activated alumina solids and solid salts of alkali metals, alkaline earth metals or ammonium ion; and contacting the gas stream with the adsorbent.
