用以校正传送信号中信号减损的通信系统及其相关方法
摘要：
本发明提供了一种用以校正传送信号中信号减损的通信系统。通信系统包含有载波信号产生器、传送模块、测试信号产生器、功率检测单元与校正装置。测试信号产生器是依据具有特定频率的单音信号或直流值与该单音信号的组合来产生第一测试信号至传送模块的第一传送路径或产生第二测试信号至传送模块的第二传送路径。功率检测单元是检测传送信号中与特定频率相关的信号成分的功率以产生功率指示信号。校正装置是运用第一候选校正参数来参考对应于第一候选校正参数的第一功率指示信号以决定目标校正参数。本发明提供的用以校正传送信号中信号减损的通信系统及其相关方法，减少了信号减损对通信系统造成的影响，提高了通信系统的效率。
摘要（英）：

A communication system for determining a target calibration parameter for calibrating impairments in a transmission signal is disclosed. The communication system includes a carrier signal generator, a transmitting module, a testing signal generator, a power detection unit, and a calibration apparatus. The testing signal generator generates a first testing signal to the first transmitting path of the transmitting module or a second testing signal to the second transmitting path of the transmitting module according to a single tone signal having a specific frequency or according to combinationsof a DC value and the single tone signal. The power detection unit detects power of components associated with the specific frequency in the transmission signal to generate a power indicating signal.The calibration apparatus applies a first candidate calibration parameter to reference a first power indicating signal corresponding to the first candidate calibration parameter to determine the target calibration parameter.
