Abstract: Provided are a method and device for estimating a channel in a wireless communication system, and more particularly, a method of estimating a channel of an uplink signal in an orthogonal frequency division multiplexing (OFDM)/orthogonal frequency division multiple access (OFDMA) communication system supporting the Institute of Electrical and Electronics Engineers (IEEE) 802.16d/e standards and a channel estimation device employing the method. The method includes the steps of: extracting pilot symbols included in the received signal and estimating linear phase values using the pilot symbols; interpolating the pilot symbols along a time axis and obtaining first channel responses; interpolating the pilot symbols along a frequency axis according to the first channel responses and obtaining second channel responses; and calculating channel estimation values using the second channel responses and the linear phase values.

Abstract: Provided is an apparatus for producing confectionery including a grain supply unit installed on a main body and uniformly supplying grains inserted from the outside, a grain processing unit rotatably installed on the main body, receiving the grains and crushing the grains using a rotating spiral, and simultaneously discharging the grains in a jellylike state using frictional heat generated during collision of the grains, and a drive unit for driving the grain processing unit and the grain supply unit.

Abstract: Provided is an apparatus for producing cereal puffs, which heats cereals under pressure by means of a continuous circulating operation, puffs the cereals several times by means of a multistage rising operation, and causes the puffed cereals, i.e. the cereal puffs, to stand by at a predetermined position, and then to be rapidly discharged in a forward direction. Thus, it is possible to process the cereal puffs in a uniform shape, and to discharge the cereal puffs in a constant direction. Further, it is possible to simultaneously produce a plurality of cereal puffs having a uniform shape by means of one heating and pressurizing operation in a single apparatus.

Abstract: Disclosed are an apparatus and a method for estimating a channel in a base station when using an Optional Partial Usage of Sub-Channels (OPUSC) mode in an uplink channel of a communication system supporting Orthogonal Frequency Division Multiplexing/Orthogonal Frequency Division Multiple Access (OFDM/OFDMA). In order to estimate the channel in the OFDM/OFDMA communication system, according to the present invention, pilots and data are extracted from input signals, phase change caused by time delay is estimated using the extracted pilots and data, and a channel estimation value is obtained by reflecting the estimated phase change.
