Abstract
Provided are a terminal performing a wake-up with consumption of low power and a wake-up method performed by the terminal. The terminal includes: a passive filter outputting a correlation signal between a received signal and a reference signal; and a wake-up controller controlling whether to wake up a communication module, using the correlation signal output from the passive filter. Thus, a wake-up signal can be processed using the passive element that does not consume power during its operation. Also, a wake-up of a communication module can be controlled using the result of processing the wake-up signal. As a result, power consumption can be greatly reduced during the wake-up.
