  • Spatial puncturing apparatus, method, and system
    Patent number: 8160028
    Abstract: Stations in a N×N multiple-input-multiple-output (MIMO) wireless network always puncture the weakest spatial channel. N?1 spatial channels are always used regardless of the channel state.
    Type: Grant
    Filed: April 1, 2010
    Date of Patent: April 17, 2012
    Assignee: Intel Corporation
    Inventor: Ada S. Y. Poon
  • SPATIAL PUNCTURING APPARATUS, METHOD, AND SYSTEM
    Publication number: 20100189091
    Abstract: Stations in a N×N multiple-input-multiple-output (MIMO) wireless network always puncture the weakest spatial channel. N?1 spatial channels are always used regardless of the channel state.

  • Spatial puncturing apparatus, method, and system
    Patent number: 7710925
    Abstract: Stations in an N×N multiple-input-multiple-output (MIMO) wireless network always puncture the weakest spatial channel. A receiving station determines channel state information for N spatial channels and feeds back to the transmitting station channel state information for only N?1 spatial channels. The channel state information may include a beamforming matrix to cause the transmitting station to utilize N?1 spatial channels.
