摘要
A method and system use the mutual coupling property of multiple antenna elements for characterizing signal waveform distortion introduced by items in the signal path, including the antenna elements, of a radio frequency transmit/receive system. The method and system alleviate the need for external test equipment by using the same hardware used in standard operation of the transmit/receive system for performing waveform distortion characterization through the generation, mutual coupling, and acquisition of a reference signal. In an embodiment involving application of complementary inverse predistortion to generation of an operational signal and/or to processing of a received operational signal, the signal as received and processed during standard system operation is compensated for distortion contributed by system hardware, improving impulse response and system performance.
