A transmission apparatus of a single carrier-based wireless communication system is proposed. The transmission apparatus may include a transceiver, a memory configured to store one or more instructions; and a processor configured to execute the one or more instructions stored in the memory. The processor may generate data symbols by modulating traffic data, generate a cyclic prefix (CP) on the basis of the data symbols, and generate a pilot symbol for the data symbol. The transceiver may transmit a single carrier frequency domain equalizer (SC-FDE) frame including the data symbol, the CP, and the pilot symbol. The data symbols may include first data symbols and second data symbols. The pilot symbol may be transmitted after transmission of the first data symbols and before transmission of the second data symbols.

Provided is a method and apparatus for selecting an airborne position reference node. A weight center coordinate of the repeaters is calculated by using position coordinates of repeaters, a plane having a vector connecting the weight center coordinate and a position coordinate of a user as a normal vector is determined, and the position coordinates of the repeaters are orthographically projected onto the plane. A certain number of repeaters located farthest from the weight center coordinate of the repeaters are selected to be airborne position reference nodes, on the basis of the orthographically projected coordinates of the repeaters and the weight center coordinate.

Apparatus and method of selecting airborne position reference node

A multiple cone type loudspeaker having a construction including a plurality of vibrating plates and a plurality of baffle plates protruded forwards from an enclosure of the loudspeaker. Each of the baffle plates serves to effectively isolate both spaces respectively defined at front and back sides of each corresponding one of the vibrating plates protruded forwards beyond the front surface of the enclosure. As a result, there is no phenomenon that the density of air is equalized in both spaces respectively defined at front and back sides of each vibrating plate as the vibration of the vibrating plate is continued. Accordingly, it is possible to achieve an extension in regeneration band, an improvement in directivity and a generation of dynamic sound.
