    Abstract: First and second input signals to be transmitted are separately modulated based on symbol mapping. A phase value is selectively adjusted for the modulated first and second input signals. The selectively phase-adjusted first and second input signals are separately angle modulated. The angle-modulated first and second input signals are transmitted.

    Abstract: The present invention relates to a transmission method, a transmission apparatus, a reception method, and a reception apparatus of a digital broadcasting signal that can add frame header information to a front portion of a transmission frame in a transmission system for digital broadcasting to thereby determine a different transmission mode, modulation level, hierarchical modulation, error correction code, and the like for each temporally different transmission frame, and a transmission frame structure thereof. The transmission frame structure includes a frame header containing multiplexing information of the transmission frame, and a frame body containing data information associated with a service provided by the transmission frame. Also, the frame header may include a frame synchronization signal unit including synchronization signal information for extracting a start position of the transmission frame and a frame information unit including multiplexing information of data contained in the transmission frame. The multiplexing information denotes information associated with a transmission mode, a modulation level, a hierarchical modulation, and an error correction code of the data contained in the transmission frame.

    Abstract: A repeater converts a frequency of a received signal based on a local oscillating frequency and transmits a transmitting signal of a frequency that is different from the frequency of the received signal. Here, the local oscillating frequency includes a local oscillating error that may be different in a plurality of repeaters. Accordingly, the repeater cancels the local oscillating frequency error itself in a frequency conversion so that transmitting frequencies between the plurality of repeaters may be identical.

    Abstract: The present invention relates to an on-channel repeating apparatus and method. An embodiment of the present invention provides an on-channel repeating method including: subtracting a replica of a feedback signal from a signal received from a main transmitter or another repeating apparatus; demodulating and equalizing the signal to remove noise, a multipath signal, and the remaining feedback signal from the signal; inserting identification signal having good correlation properties into the signal; modulating the signal; and transmitting the modulated signal. Another embodiment of the present invention provides an on-channel repeating apparatus including: a unit that converts signals received from a main transmitter or another repeating apparatus into signals in a predetermined band; a unit that generates identification signals having good correlation properties; a unit that generates a replica from the signals in the predetermined band and the identification signal, and then removes a feedback signal; a unit that demodulates a signal from which the feedback signal is removed; a unit that equalizes the demodulated signal to remove noise, a multipath signal, and the remaining feedback signal therefrom; a unit that inserts the identification signal into the equalized signal; and a unit that modulates the signal having the identification signal inserted thereinto and transmits the modulated signal. According to the present invention, the repeating apparatus repeats output signals that have a small time delay and whose distortion is corrected. Therefore, it is possible to improve the utilization of limited frequency sources, and reduce investment in achieving a repeating apparatus.
