Digital signal processing is currently in a period of rapid growth caused by recent advances inVLSI technology. This is especially true of three areas of optimum signal pro- cessing; namely, real-time adaptive signal processing, eigenvector methods of spectrum estimation, and parallel processor implementations of optimum filtering and prediction algorithms. In this edition the book has been brought up to date by increasing the emphasis on the above areas and including several new developments. The major additions are: a unified presentation of the fast recursive least-squares algorithms for adaptive pro- cessing; the discussion of several eigenvector methods of spectrum estimation such as MUSIC, minimum-norm, ESPRIT, spatial smoothing for coherent signals,.
