    • PURPOSE: Wireless power transmission apparatus is provided to design a resonator, which has high Q factor, and adaptively match impedance, thereby effectively conducting wireless power transmission even when user freely positions a mobile terminal on a charging pad. CONSTITUTION: Wireless power transmission apparatus comprises; a transmission electric power converting section (211) which converts direct current (DC) power into alternating current (AC) power; a control unit (213) which adjusts a Q factor of a transmission resonator by using the frequency of the transformed AC power and resonant frequency of a transmission resonator, and controls adaptive impedance matching; a transmission resonator (212) which wirelessly transmits the transformed AC power to a receiver through the controlled adaptive impedance matching and the adjusted Q factor; and a transmission resonator (212) which has a coil installed in the transmitter. [Reference numerals] (211) Transmission electric power converting section; (212) Tx resonator; (213,216) Control unit; (214) Rx resonator; (215) Receiving electric power converting section; (217) Battery

    • PURPOSE: A method and an apparatus for modulating a frequency hopping in a communication system are provided to improve communication performance by reducing interference with other wireless communication signals. CONSTITUTION: A frequency hopping pattern is generated according to the level of a hopping frequency. The hopping frequency is generated by using a frequency hopping pattern. The hopping frequency is modulated into the frequency hopping diffusion signal by multiplying the hopping frequency by an original signal. A chirp pulse code is generated to vary the hopping diffusion signal. A chirp pulse signal is generated by multiplying the frequency doping diffusion signal with the chirp pulse code. One frequency hopping or more are generated according to a wireless communication method.
