Abstract: The present invention relates to a transmitter in a frequency division multiple access communication system. The transmitter generates a plurality of pilot symbols, and groups the plurality of pilot symbols into a plurality of groups according to a location of a subcarrier. In addition, the transmitter inverse fast Fourier transforms the pilot symbol in each group, and sequentially outputs a first pilot symbol sequence corresponding to each group. The transmitter generates a plurality of pilot blocks respectively corresponding to the plurality of groups, and converts the first pilot symbol sequence of each group into a second pilot symbol sequence of a corresponding pilot block among the plurality of pilot blocks.

Abstract: A photosensitive drum protecting device for use in a color electrophotographic printer is provided. The printer, in which developing device cartridges of various colors including photosensitive drums and developing rollers are installed, and a printing path contacting the photosensitive drums is formed, includes a photosensitive drum protecting device that simultaneously exposes or protects each of the photosensitive drums. All of the photosensitive drums disposed at front end portions of the developing device cartridges are covered by just one photosensitive drum protecting device. Thus, the complexity of the printer is reduced and the printer can be made more compact.

Abstract: Provided is a duplex printer and method of duplex printing. The duplex printer and method of printing includes a paper feeding belt that is vertically installed to form a first vertical surface; a photosensitive drum that is installed to contact the first vertical surface; and a transfer roller that is installed to contact an other surface of the first vertical surface contacting the photosensitive drum to transfer a toner image from the photosensitive drum onto a sheet of paper, which is supplied between the photosensitive drum and the paper feeding belt. A back surface feeding path of the paper is formed at an opposite side of the photosensitive drum in the paper feeding belt, and the paper is conveyed closely adhered to a surface of the paper feeding belt in the back surface feeding path of the paper. Accordingly, since the paper feeding belt is used as the back surface feeding path of the paper, the number of additional devices such as guide plates and convey rollers can be reduced, and a compact color printer can be fabricated.
