  • Patent number: 7864657
    Abstract: A method and apparatus for performing stream weighting in a spatial-division multiple access communication system is provided herein. During operation the base station receiver receives channel information from mobiles (also known as users or nodes) and calculates transmit antenna weights that that maximize the power delivered to each mobile while allowing for a small amount of crosstalk to exist between users. Information or data is transmitted to the nodes utilizing the appropriate stream weights. By allowing tolerable amounts of cross talk, the coherent gain to the desired SDMA user can be increased, and thus the overall performance is improved.

  • Patent number: 7095439
    Abstract: A method and an image sensor circuit (2) for providing a bit stream pulse modulated signal at a controlled bit rate. The image sensor circuit (2) has a two-dimensional array of pixel signal pulse frequency modulators (22) each having a photodiode (32) for converting incident light into a varying signal voltage and a frequency-to-digital converter which generates a pulse frequency modulated signal from the varying signal voltage. The circuit 2 also has a sampling unit (24) which samples the pulse frequency modulated signal to generate the bit stream pulse modulated signal at said controlled bit rate. An arithmetic unit (26) is coupled to an output of the sampling unit (24) for performing stochastic processing on the bit stream pulse modulated signal.

  • Patent number: 7085256
    Abstract: A method (S200) and system for scheduling data transmissions between a base station (110) and a plurality of user terminals (130) in a wireless network. The method and system include transmitting a first poll (260) from the base station (110) to a first user terminal traffic stream (Step S210). In response to the first poll (260) the first user terminal traffic stream transmits a first frame (210) to the base station (110), where a queue state of the first user terminal traffic stream is indicated in the header of the first frame (210) (Step S220). The base station (110) removes the first user terminal traffic stream from an active list when the first frame (210) indicates that the queue state is empty (Step S230). The base station (110) then calculates a deferral window (220) and schedules transmissions of other data frames (240) between the base station (110) and the plurality of user terminal traffic streams that remain on the active list (Steps S240 and S250).

  • Patent number: 6961311
    Abstract: A method (600) performed by a packet scheduler of an access point (215) of adaptively resizing a scheduling window in a Quality of Service enabled Local Area Network (200) is disclosed. The packet scheduler schedules data packets for a given duration, termed a scheduling window. The packet scheduler according to an embodiment of the invention adaptively changes the duration of the scheduling window based on the QoS requirements of data packets to be transmitted to and from the access point (215). In particular, the duration of the scheduling window is changed based on the delay requirement of the data packet having the most constraint QoS requirement.

  • Patent number: 6922564
    Abstract: A method, a network access point and a communication system are disclosed for admitting data flows corresponding to new service requests to a multiple access network. The method includes the steps of receiving a service request having Quality of Service (QoS) requirements from a network node (410), calculating the effective bandwidth required by a data flow corresponding to the service request based on an average packet size of the data flow (420), determining the maximum capacity of the network (430), and admitting the data flow corresponding to the service request (445) if the network has sufficient capacity to accommodate the effective bandwidth required by the data flow. The average packet size of a data flow corresponding to the service request can be determined from the service request for calculating the effective bandwidth required by the data flow. The maximum capacity of the network can be determined based on the number of transmitting nodes in the network.

  • Patent number: 6807317
    Abstract: A method (200) and decoder system (100) for reducing quantization effects or ringing artifacts imposed upon decoded image of hybrid block based coding schemes such as MEPG and H 261. The system (100), in use, and method (200) receive (220) decoded image decoded blocks that were decoded from transform coded blocks quatized by a selected quantization parameter. The system (100) and method (200) then analyze (230) selected pixel values of selected pixels with neighboring pixel values of associated neighboring pixels in the decoded blocks to determine difference values for each of the selected pixels. Potential object edges, of the decoded image represented by the decoded blocks, are then detected (240) to identify the selected pixels as edge pixels, the detecting is effected by comparing the difference values with selected threshold values that are determined with respect to the selected quantization parameter associated with the blocks.

  • Patent number: 6777629
    Abstract: A meso-scale MEMS device having a movable member (51) is formed using standard printed wiring board and high density interconnect technologies and practices. In one embodiment, sacrificial material disposed about the movable member (51) is removed through openings (101, 102) as formed through a cover (91) to form a cavity (121) that retains and limits the freedom of movement of the movable member (51). The movable member can support a reflective surface (224) to thereby provide a mechanism that will support a projection display and/or image scanner (such as a bar code scanner).

  • Patent number: 6711534
    Abstract: A method of analyzing a circuit having a structural loop between different channel connected components within the circuit first splits the circuit into its constituent channel connected components (100). The structural loops are then detected and broken (101) before obtaining a pair of boolean functions at each break point (102) by inserting a pair of temporary boolean variables at the break point on a boundary between different channel connected components and analyzing each channel connected component in the structural loop utilizing the pair of temporary boolean variables to obtain the pair of boolean functions representing the functionality of the circuit at the break point. The pair of boolean functions are then analyzed (103) to determine whether the structural loop is sequential in nature, and, if so, the pair of boolean functions is modified (105) in order to remove any dependence in the pair of boolean functions on the pair of boolean variables.

  • Patent number: 6690748
    Abstract: A digital IF to base band demodulator (120) includes delta sigma samplers (202, 204) for sampling two channels of an IF signal at a sampling rate that is substantially higher than the Nyquist rate for the IF signal. A first pair of decimation filters (206, 208) decimates and filters the output of the delta sigma samplers (202, 204) but keeps the samples at a rate sufficient to perform digital mixing, cross adding, and pulse shape match filtering. A set of mixers (210, 212, 214, 216) mixers the output of the first pair of decimation filters with two phases of a digital representation of an local IF signal. A pair of summers (222, 224) sums, and subtracts outputs of the set of mixers (210, 212, 214, 216) in order to cancel undesired harmonics. A second set of decimation filters (226, 228) decimates and filters the output of the summers (222, 224) applying a filter function that is matched to a pulse shape of a base band signal present in the IF signal.

  • Patent number: 6675278
    Abstract: A method and apparatus of managing a memory (2) having a number of pages (5) involves mapping the physical pages (5) to corresponding pages (4) in a logical address space (1) using a map table (3). When the number of pages utilised by an application increases or decreases, or if an application is deleted or a new application is loaded, the physical pages used by the remaining applications are unchanged, but the logical pages are moved so that the logical pages used by a single application are contiguous and so that the unused pages are contiguous. Thus, after moving the logical pages, the mapping of the logical pages to the physical pages is updated and a free page pointer (6) indicates the next available free logical page.
