Abstract: The present invention relates to an apparatus and a method for implementing a wideband multicarrier by using complex digital modulation. With a conventional analog quadrature modulation, which has been used to modulate a complex digital signal into an intermediate frequency (IF) signal or a radio frequency signal, it is difficult to obtain a precise local oscillator signal. Analog circuits, as many as the number of desired carrier signals in a multicarrier, are required. However, the invention implements a wideband multicarrier by newly employing a digital channelizer and a digital IF modulation portion. Since the former can efficiently generate a plurality of carrier signals having different center frequencies and the latter can up-convert the generated carrier signals into a desired multicarrier, the invention can obtain a more reliable wideband multicarrier and implement a wideband multicarrier in a cost-effective manner.

Abstract: The present invention relates to a power control method in a two-way relay network, and provides a power control method in a two-way relay network in which a minimum transmission rating and a synthesized transmission rating of the overall system are magnified if there are restrictions on the synthesized power of terminals and a repeater in the two-way relay network in which two terminals transmit and receive data through the repeater. To this end, the power control method in the two-way relay network of the present invention comprises the steps of: determining the ratio of power allocated to the respective terminals and the repeater according to each subcarrier, under the restrictions on the synthesized power of each terminal and the repeater; and determining power allocated to each subcarrier according to the determined power allocation ratio.
