APPARATUS AND METHOD FOR MULTIPORT AMPLIFICATION IN COMMUNICATION SYSTEM

摘要

PURPOSE: A multiport amplifying device in a communications system and a method thereof are provided to normally transmit and receive signals being transmitted through multiple beams. CONSTITUTION: A multiport amplifying device comprises amplifying parts (420,422), an calculating part (430), and a correcting part (410). The amplifying part amplifies an input signal inputted through the multiple input ports for outputting the amplified signals to multiple output ports. The amplifying part amplifies the input signal in which phase errors or amplitude errors are corrected for outputting to the multiple output ports. The calculating part detects the phase errors or amplitude errors of the input signal for calculating the phase error value or amplitude error value of the input signal. The correcting part corrects the phase errors or amplitude errors of the input signal through the phase error value or amplitude error value of the input signal.
