Abstract

The Letter shows how the accuracy and dynamic range of bandpass impulse response measurements using pseudorandom noise can be improved by removing the DC offset of the PN sequence autocorrelation function from the desired impulse response. This method can be quite easily implemented in the frequency domain.
