A New Method for Estimating the Bandwidth using Two-Channel Narrowband Signals with Strong Interference

摘要：

Bandwidth is an important parameter in signal processing. A novel method for estimating the bandwidth using the linear phase relationship between two-channel narrowband signals is proposed. The two-channel model is based on the time-difference of arrival (TDOA) estimator. The second channel signal is a time delay copy of the first channel. The comparison between the proposed method and the general ones is presented. It is shown that the method is effective for signals corrupted by strong interference even at low SNR.
