Abstract

A novel acoustooptic architecture that implements linear least-mean square adaptive filtering and prediction and has the potential for very wide bandwidth signal processing is described and analyzed in this paper. This architecture maintains coherent operation (providing complex weights) and employs a single acoustooptic device, a photodiode, and a laser diode. The application of a multichannel acoustooptic processor to multiple antenna adaptive interference cancellation is then presented.
