Abstract
A noise removal algorithm based on short-time Wiener filtering is described. An analysis of the performance of the filter in terms of the processing gain, mean square error, and signal distortion is presented. A generalized form of the filter is also discussed and results of applying the algorithm to some typical underwater acoustic data are presented
