Abstract: PURPOSE: An energy transmission system in a communication system and a method thereof are provided to transmit multi-energy through multi-channel communication in the communication system, thereby maximizing frequency utilization efficiency. CONSTITUTION: A reflected wave separation and path determination part(100) with respect to a radio frequency(RF) signal passes a broadband RF signal to a channel selector(200) with respect to RF reception for a demodulation process. The channel selector passes a channel selected by a user. An energy regeneration part(300) regenerates energy with respect to the RF signal reflected from the channel selector. A narrow-band RF signal which passes the channel selector is processed in a data processing part(400) in order to be utilized as a communication signal. The reflected broadband RF signal is converted into DC energy required in a receiving device.

Abstract: Provided is a method and apparatus improving a deterioration of a gain flatness and a phase characteristic that may be incurred while a baseband signal is transformed into a immediate frequency (IF) signal and a radio frequency (RF) signal in a broadband wireless communication system. A sub-band extractor may divide the broadband signal into multiple sub-band signals, may pre-compensate for a gain and a phase delay of each sub-band signals in the baseband, and may combine the pre-compensated sub-band signals into the single broadband signal and thus, the deterioration of the gain flatness and a phase delay flatness that may be incurred while the broadband signal is transformed into the IF signal and the RF to signal, may be improved.
