  • System and method for cooperative spectrum sensing in cognitive radio systems
    Patent number: 8442567
    Abstract: A system and method for cooperative spectrum sensing in cognitive radio (CR) systems is provided. A method for CR user operation includes coordinating with partner CR users to share spectrum sensing information, combining spectrum sensing information from partner CR users, and determining if a transmission opportunity exists based on the combined spectrum sensing information. The method also includes transmitting a message to a CR user if the transmission opportunity exists, and storing the message if the transmission opportunity does not exist.
    Type: Grant
    Filed: March 19, 2010
    Date of Patent: May 14, 2013
    Assignee: FutureWei Technologies, Inc.
    Inventors: Dongdong Li, Dandan Wang, Mazin Al-Shalash, Anthony C. K. Soong, Guodong Zhao, Chenyang Yang
  • Black silicon based metal-semiconductor-metal photodetector
    Patent number: 8384179
    Abstract: A black silicon based metal-semiconductor-metal photodetector includes a silicon substrate and a black silicon layer formed on the silicon substrate. An interdigitated electrode pattern structure is formed on the black silicon layer, which can be a planar or U-shaped structure. A thin potential barrier layer is deposited at the interdigitated electrode pattern structure. An Al or transparent conductive ITO thin film is deposited on the thin potential barrier layer. A passivation layer is provided on the black silicon layer. In the black silicon based metal-semiconductor-metal photodetector, the black silicon layer, as a light-sensitive area, can respond to ultraviolet, visible and near infrared light.
