    • A network test system and a test method are provided to provide a destination unlimitedly by using single equipment by providing an environment as if a destination existed although it does not actually exist. An external network system(10) generates traffic including an attack to a network. An internal network system(20) includes a destination of the generated traffic and a destination of the attack. A routing device(30) transmits multiple packets of the traffic to a corresponding destination in association with the external network system(10) and the internal network system(20). The routing device(30) is set to transfer the packets only from the external network system(10) to the internal network system(20), tests performance of the internal network system(20) with respect to the attack, and performs a security function to generate a log with respect to the traffic transmitted to the internal network system(20).

    • 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. .
