其他摘要：This paper proposes the important issues in signal segmentation . The signal is disturbed by multiplicative noise where the number of segments is unknown. A Bayesian approach is proposed to estimate the parameter. T he parameter includes the number of segments, the location of the segment, and the amplitude . T he posterior distribution for the parameter does not have a simple equation so that the Bayes estimator is not easily determined. Reversible Jump M arkov chain M onte C arlo (MCMC) method is adopted to overcome the problem. The Reversible Jump MCMC method creates a Markov chain whose distribution is close to the posterior distribution. The performance of the algorithm is shown by simulation data. T he result of this simulation shows that the algorithm works well. As an application, the algorithm is used to segment a Synthetic Aperture Radar ( SAR ) signal. The advantage of this method is that the number of segments, the position of the segment change, and the amplitude are estimated simultaneously.
