Abstract: The present invention provides a multi-channel array distortion compensation apparatus and method. The apparatus determines, according to a status of a first indication signal, whether to trigger a signal compensation operation; determines, according to a status of a second indication signal, a first adjustment condition is met, compares power of a received signal with a power threshold, and if the power of the received signal is greater than the threshold power, compensates the received signal according to a first adjustment factor; and if the status of the second indication signal does not meet the first adjustment condition, determines the status of the second indication signal meets a second adjustment condition, performs auxiliary compensation according to a second adjustment factor. By compensating signal distortion caused by chip stacking for a received signal, this reduces costs for implementing a multi-channel array system without the need to increase system complexity.
