    摘要： Provided is an apparatus and method for communicating data in a hybrid diversity mode in a broadband wireless communication system. In a method for transmitting data to a subscriber station (SS) in the broadband wireless communication system, null subbands are determined using feedback information received from the SS. TX data to be transmitted to the SS are mapped to a diversity zone from which the null subbands has been excluded. The mapped data are OFDM-modulated and transmitted to the SS. In this way, frequency subbands with poor channel conditions are excluded from data transmission. Accordingly, it is possible to enhance the FER performance and transmit data at a high MCS level.

    摘要： Channel state indication signals are transmitted to communication stations via wireless channels and SINR (Signal to Interference and Noise Ratio) values of the channel state indications signals or channel environment parameters according to the SINR values are received from the communication stations as feedback signals. A channel estimation apparatus includes: an average measurement unit for measuring average values of the feedback signals over a period of time, each of the average values being an average value of feedback signals received from an identical communication station during the period of time; and a channel evaluation unit for estimating wireless channel quality of each communication station according to a geographical environment thereof based on the average values measured by the average measurement unit.

    摘要： A method for forming fine patterns includes (S1) closely contacting a cliche-forming film to a hard mold concavely patterned, thereby making a disposable cliche; (S2) coating an elastic blanket cylinder with ink or resin; (S3) compressing the elastic blanket cylinder to the disposable cliche to remove ink or resin on a surface of the elastic blanket cylinder at a portion contacting with a relatively protruded embossed portion of the disposable cliche; and (S4) transcribing ink or resin remaining on the surface of the elastic blanket cylinder to a substrate. This method allows simple and fast works and greatly reduces costs by adopting a disposable cliche that may be easily installed and removed. Also, this method may be effectively utilized to form a fine pattern of an electronic device or a display device such as color filter and electrode.
