    • A capsule endoscope according to the present invention comprises: a body including a photographing unit, a control unit and a battery to supply power; and an expansion unit which is mounted at one side of the body and includes first porous hydrogels for absorbing water to be expanded in the inside of the body and second hydrogels for absorbing water later than the first porous hydrogels to be expanded. The capsule endoscope and the method for operating the same are capable of photographing lesion in a small intestine while stably maintaining the photographed location by the primary expansion in the small intestine and photographing lesion in a large intestine while stably maintaining the photographed location by the secondary expansion of the expansion unit in the large intestine, thereby performing continuous endoscopy for the small intestine and the large intestine without using the existing endoscope for the large intestine.

    • PURPOSE: An offset phase rotation shift keying(OPRSK) modulation apparatus and a method, a phase silence rotation shift keying(PSRSK) modulation apparatus and a method, a phase silence rotation shift keying demodulation apparatus and a method are provided to reduce a nonlinear distortion in an environment in which the nonlinear distortion exists by applying a power dissipation and a phase offset of a symbol section at the same time, based on a modulation method of high power efficiency, for a low power WBAN system. CONSTITUTION: An offset phase rotation shift keying modulation apparatus comprises a symbol generating unit(610) generating a symbol having a phase offset of 45° by a constellation shaft of a first effective symbol section located in a front part and a constellation shaft of a second effective symbol section located in a rear part when performing a modulation positioning a signal waveform in the front part or the rear part among the total section of the symbol based on the three inputted bit information, and a transmission unit(620) transmitting the generated symbol. .
