  • Publication number: 20150043436
    Abstract: Embodiments are provided for a cooperative cross-tier precoding (CTP) and intra-tier precoding (ITP) scheme for two-tier networks. The cooperative precoding scheme allows exploitation of extra transmit dimensions at the second-tier network, thereby increasing the achievable throughput at the second-tier network. The embodiments allow significant increase in throughput of the second-tier network due to both CTP between the second-tier network and the first-tier network, and efficient ITP between the second-tier network transmitters. The increase in transmit dimension allows for efficient linear inra-tier precoding, which significantly reduces the intra-tier interference. A processor coupled to the second-tier network transmitters is configured to perform CTP of transmit signals in the second-tier network for cancelling signal interference from the second-tier network transmitters to a first-tier network receiver, thereby generating CTP matrix information.

  • Patent number: 8954392
    Abstract: The efficiency of data de-duplication may be improved by storing related file data in a single container, or in multiple linked containers, of a history. Additionally, the efficiency of data de-duplication may be improved when shorter hash tables are used to reference historical data in a history. Shorter hash tables may be achieved by storing fewer than all the hash values obtained for a given amount of historical data. Further, the efficiency of data de-duplication may be improved by comparing related incoming file data with historical data from a container without hashing/chunking the remaining file data upon matching an earlier chunk of the incoming file data to the container.
