Obadamilola Aluko has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method and apparatus for sharing channel state information (CSI) in a multiple-user multiple-input multiple-output (MU-MIMO) environment
    Patent number: 8976850
    Abstract: Provided is a channel state information (CSI) sharing method and apparatus in a Multiple User Multiple Input Multiple Output (MU-MIMO) environment. Each node may use network-coding to reduce overhead necessary for sharing CSI between all nodes in the MU-MIMO environment. A transmitter may dynamically select, based on the CSI between receivers, a path used for transmitting data to each receiver and a receiver to be used as a relay based on the global CSI. A decoding performance may be improved based on the CSI between the transmitter and the receivers.
    Type: Grant

  • Clustered multi-cell multi-user multiple input multiple output communication system using cell-edge user selection scheme
    Patent number: 8599751
    Abstract: Provided is a control method of a control apparatus for a multi-cell communication system including a plurality of cells, the method including determining a cell edge terminal or an inner cell terminal from each of terminals included in each of the cells, and selecting, from base stations included in the plurality of cells, a first base station and a second base station. The first base station may serve all of a corresponding cell edge terminal and a corresponding inner cell terminal, and the second base station may serve only the corresponding inner cell terminal between the corresponding cell edge terminal and the corresponding inner cell terminal.

  • Perturbed decoder, perturbed decoding method and apparatus in communication system using the same
    Patent number: 8254482
    Abstract: A decoder adopted to receive a signal transmitted in a communication system, includes one or more of a module adopted to pre-process a received signal to reduce the effect of interference-plus-noise on the received signal before filtering the received signal, and a module adopted to post-process the result of filtering the received signal.
