Abstract: Provided is an apparatus for enhancing power efficiency, the apparatus including a magnetic substance configured to generate a magnetic field, a conductive wire configured to pass the magnetic field, and of which one end is electrically connected to a power line to which alternating current (AC) is applied, and a controller connected to another end of the conductive wire, and configured to apply, to the conductive wire, and to prevent a sudden overcurrent a voltage surge from flowing into an electric device. The conductive wire includes a conductive plate, and the conductive plate is disposed in a space in which the magnetic field is generated to be separate from the magnetic substance, and a first width of the conductive plate can be the same as or greater than a second width of the conductive wire.

Abstract: A link adaptation system using a Doppler frequency is provided. The link adaptation system includes: a Doppler frequency estimation unit to estimate a Doppler frequency of a signal transmitted via a wireless channel; a Signal to Noise Ratio (SNR) measurement interval determination unit to determine an SNR measurement interval of the signal transmitted via the wireless channel based on the estimated Doppler frequency; and an SNR measurement unit to measure an SNR of the signal based on the determined SNR measurement interval.
