摘要：A method to test a signal path with vacant bandwidth by sending a test signaltwice and processing two resulting nonlinear distortion signals captured in the vacantbands to determine presence of nonlinear distortion. If the signals correlate, the energy
in the vacant bands is nonlinear distortion. If the test signal is sent followed by an inverse(in time-domain) of itself, and a resulting correlation peak is negative, the nonlineardistortion is determined to have been created by odd-order nonlinear distortion.
