    Abstract: PURPOSE: A transmission and reception apparatus and method thereof are provided to create discontinuous interference signals by embodying variable data throughout without controlling a modulation parameter. CONSTITUTION: A data rate control unit outputs input data bit strings to a group unit according to target data rates(S710). The group unit groups the inputted data bit strings(S720). A first modulation unit modulates a part bit of a group in a FSK(Frequency Shift Keying) modulation method based on duty(S730). A second modulation unit modulates the other bits in PSK(Phase Shift Keying) modulation method(S740). A signal transmission unit creates transmission signals(S750).

    Abstract: PURPOSE: A wake-up signal communication system, apparatus, method, and wireless terminal are provided to increase the number of wake-up target wireless terminals wake-up signal transmission distances and coverage by using a center wake-up system. CONSTITUTION: A detector(340) creates signals rectified by the rectification of a first wake-up signal. A code generation apparatus(350) outputs code signals corresponding to codes of a wake-up target terminal. A comparator(360) creates a second wake-up signal transmitted to the wake-up target terminal by using the rectified signal and the code signal. The rectified signal is inputted to a non-inverting terminal of the comparator.
