  • Extrapolating Channel State Information ("CSI") Estimates From Multiple Packets Sent Over Different Frequency Channels to Generate a Combined CSI Estimate for a MIMO-OFDM System
    Publication number: 20150078470
    Abstract: A method for extrapolating channel state information (“CSI”) estimates from multiple packets sent over different channels to generate a combined CSI estimate for a MIMO-OFDM system is disclosed. Packets are received on an m×n×Wi channel configuration, wherein m is the number of receive antennas used to receive the packets, n is the number of transmit antennas used to transmit the packets, and Wi is the number of OFDM channels for a packet i in the MIMO-OFDM system. CSI estimates are generated for the received packets and the CSI estimates are extrapolated to generate a combined CSI estimate for an m×n×R channel configuration, wherein R>Wi.

  • Multiple-source data compression
    Patent number: 8554746
    Abstract: One embodiment of the present invention is directed to a method for compressing data generated by multiple data sources. The method includes steps of partitioning data generated by the multiple data sources into data partitions, the data included in each data partition containing inter-data-source redundancies and, for each data partition, compressing the data in the data partition to remove the inter-data-source redundancies.

  • Synchronization in a wireless node
    Patent number: 8279897
    Abstract: A wireless node receives a beacon from a wireless access point. The beacon includes a wireless protocol time synchronization function (TSF) timestamp generated with reference to a global clock for a network. The wireless node synchronizes a counter according to the TSF timestamp. The wireless node receives a global timing offset (GTO) packet from the wireless access point and combines the GTO packet with a counter value to generate a global timestamp.
