摘要
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 combinations of 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.
