摘要: A method for determining a nonlinearity characteristic of a receiver path includes generating a set of N×M digital samples by repeating N times selecting an scaling factor from a set of N scaling factors, generating a version of a test signal, the version of the test signal corresponding to a test signal scaled by the respective scaling factor, processing the respective version of the test signal in at least a part of the receiver path to generate a respective processed signal, and storing M digital samples corresponding to the respective processed signal. Fourier-transformed data are generated using at least a portion of the set of N×M digital samples and a nonlinearity characteristic of the receiver path is determined based on the Fourier-transformed data.
