  • Method for achieving transmission diversity in a multiple antenna system
    Patent number: 8311150
    Abstract: A method for achieving transmission diversity in a multiple antenna system is disclosed. The transmission diversity method includes selecting a column vector from a matrix DETERMINED according to a resource index and a current rank, and multiplying the selected column vector by a transmission symbol.
    Type: Grant

    Date of Patent: November 13, 2012
    Assignee: LG Electronics Inc.
    Inventors: Wook Bong Lee, Moon Il Lee, Bin Chul Imh, Jin Young Chun
  • Method for transmitting and receiving precoded signal in MIMO communication system
    Patent number: 8275063
    Abstract: A method for transmitting and receiving a precoded signal in a Multi-Input Multi-Output (MIMO) communication system is provided. In the method, a preceding matrix is selected from a codebook including one or more preceding matrices of each rank, each of the preceding matrices including a unitary matrix modified by an antenna selection element. A signal for transmission is then precoded by applying the selected preceding matrix to the signal for transmission and the precoded signal is transmitted through a selected antenna.

  • Method for transmitting and receiving data using pilot structure
    Publication number: 20090262845
    Abstract: A method for efficiently transmitting and receiving data in a wireless access system and a pilot allocation structure for the same are provided. In the method, data is transmitted using a resource block constructed taking into consideration channel estimation capabilities and data transfer rate and data is received using the resource block. The resource block includes a predetermined number of pilot symbols constructed in a predetermined pattern and the pilot symbols are allocated to the resource block at a predetermined allocation rate taking into consideration the number of transmit antennas.
