  • Virtual aggregation of fragmented wireless spectrum
    Patent number: 9686062
    Abstract: Method and apparatus for aggregating spectrum in which multiple disjoint blocks of spectrum may be configured as one virtual contiguous block of spectrum by modulating onto each disjoint blocks of spectrum a respective portion of a data stream in which the data rate associated with the modulated portion is compatible with the available bandwidth of the disjoint spectrum block upon which is modulated.
    Type: Grant
    Filed: March 4, 2011
    Date of Patent: June 20, 2017
    Assignee: Alcatel Lucent
    Inventors: Vinay Purohit, Paul A. Wilford
  • Distributed fragments file system
    Patent number: 9436842
    Abstract: The present invention relates to a distributed storage scheme, wherein every file is optionally encrypted, optionally interleaved, fragmented, and the various fragments stored on different constituent storage systems commensurate with the storage mechanisms supported by those storage providers.
    Type: Grant
    Filed: August 18, 2014
    Date of Patent: September 6, 2016
    Inventor: Vinay Purohit
  • DISTRIBUTED FRAGMENTS FILE SYSTEM
    Publication number: 20150052354
    Abstract: The present invention relates to a distributed storage scheme, the distributed storage scheme, every file is encrypted, interleaved and fragmented, and the various fragments are stored on different constituent physical file systems.

  • Methods and apparatuses for estimating time delay and frequency offset in single frequency networks
    Patent number: 8116419
    Abstract: In one method, an uplink signal carrying at least one block of transmitted samples is transmitted, and a distorted copy of the uplink signal is received as a downlink signal. A plurality of blocks of received samples are generated based on the received downlink signal, and a time delay and frequency offset between the uplink and downlink signals are determined based on a correlation between the block of transmitted samples and at least one of the plurality of blocks of received samples.
