Abstract: A transmission apparatus couples a first phase modulation signal for first input data and a second phase modulation signal for second input data according to a first coupling method and transmits the coupled signal, and a reception apparatus receives the coupled signal. The reception apparatus derives a signal in which a first phase modulation signal and a second phase modulation signal are coupled according to a second coupling method from a received signal and separates the first phase modulation signal and the second phase modulation signal from the received signal based on the received signal and the derived signal. Furthermore, the reception apparatus obtains the first input data by demodulating the first phase modulation signal and obtains the second input data by demodulating the second phase modulation signal.

Abstract: A method of estimating an integer frequency offset and compensating for the integer frequency offset by an estimated error is provided. A frequency offset estimation method may include receiving a reception signal including PLC data and a physical layer link channel (PLC) preamble, detecting first position information on a position of a subcarrier of the PLC preamble in a frequency axis from the reception signal through a cross-correlation between the PLC preamble and the reception signal, detecting second position information on the position of the subcarrier of the PLC preamble defined in a transmission end by restoring the PLC data, and calculating a frequency offset by comparing the first position information with the second position information.
