METHOD AND APPARATUS FOR TRANSMITTING SIGNAL, APPARATUS FOR DETECTING INFORMATION

摘要

PURPOSE: A method and an apparatus for transmitting a signal and an information detection device are provided to reduce a signal interference phenomenon by detecting respective voltage values of a plurality of subcarrier comprising an interference signal. CONSTITUTION: A data generator(110) generates transmission data. An interference signal detection module(130) generates interference signal detection information including the information about respective voltage values of a plurality of subcarriers from the interference signal. An ultra-wideband communication module(150) generates an ultra-wideband signal by modulating transmission data with an ultra-wideband method according to the interference signal detection information. The interference signal detection module includes a Fourier converter which generates subcarrier data corresponding to the subcarriers. The interference signal detection module includes a voltage detector which detects the information about respective voltage values of the subcarrier from the subcarrier data.
