| 中文摘要 | It is important to estimate the multipath time delay in underwater communication and target positioning. Based on the good time delay resolution, wideband signal is used to estimate time delay conventionally, in some situation, it is hard to use wideband signals. Focused on the narrowband signal multipath time delay estimating, an algorithm based on spectral subtraction in logarithm domain was proposed. Compared to the complex cepstrum method, the proposed method effectively improved the anti-noise ability and adapted better to the doppler frequency shift of the signal. |
