Abstract: A low power communication system and a communication method thereof are provided to reduce the power consumption by being switched into an operational mode only when a signal received at a deep sleep mode is identical to a preset wakeup signal. A detector(110) detects a signal received through an antenna, and a comparator(120) is operated by a first clock. The comparator compares the detected received signal with a preset reference voltage. When a comparison signal is outputted from the comparator, a wakeup determiner(130) is operated through the compensated second clock by corresponding to the first clock. The wakeup determiner judges an operation mode through the comparison of the compared signal with the preset wakeup signal. If the operation mode is judged, the wakeup determiner outputs an enable signal.
