Abstract : A significant amount of research into noise cancellation techniques is being conducted by the sonar community. Due to the dynamic nature of the noise and other demanding features of the sonar environment, the techniques under development make use of digital adaptive filters. Most all digital adaptive filters are basically convolution or transversal filters. The objective of the work has been to experimentally develop an iterative design procedure for an adaptive digital recursive filter suitable for use as the estimation filter in an adaptive noise cancellation system.
