  • Publication number: 20100238979
    Abstract: A method for transmitting signals for interference randomization is disclosed. The method for transmitting signals includes spreading the transmission signals using a plurality of orthogonal codes and transmitting the transmission signals spread by the plurality of orthogonal codes by a spatial frequency block coding (SFBC) or spatial time block coding (STBC) scheme. Among the plurality of orthogonal codes, codes of which mutual interferences are equal to or greater than a predetermined threshold are grouped to the same group, and orthogonal codes belonging to different groups are used for the spreading of the signals which are transmitted at the same timing. Accordingly, it is possible to realize interference randomization.

  • Patent number: 7479445
    Abstract: Methods of forming field effect transistors include forming a first electrically insulating layer comprising mostly carbon on a surface of a semiconductor substrate and patterning the first electrically insulating layer to define an opening therein. A trench is formed in the substrate by etching the surface of the substrate using the patterned first electrically insulating layer as an etching mask. The trench is filled with a gate electrode. The first electrically insulating layer is patterned in an ambient containing oxygen. This oxygen-containing ambient supports further oxidation of trench-based isolation regions within the substrate when they are exposed by openings within the first electrically insulating layer.

  • Patent number: 7458230
    Abstract: A refrigerator is provided with an airflow passage for an ice making compartment of the refrigerator. In the refrigerator, a main body has an opened side, and a door selectively closes the opened side of the main body. An ice making compartment is formed in the door, the ice making compartment being insulated from the outside and being kept at a low temperature. A duct is formed in the main body for exchanging cooling air with the ice making compartment, and a cooling air passage is formed at an outer surface of the ice making compartment to connect the duct with the ice making compartment. A switching unit closes the cooling air passage when the door is opened, and opens the cooling air passage when the door is closed. With this arrangement, the cooling air can be sufficiently supplied to the ice making compartment without the penetration of foreign substance.
