There has been a great deal of material in the area of discrete-time transforms that has been published in recent years. This book does an excellent job of presenting important aspects of such material in a clear manner. The book has 11 chapters and a very useful appendix. Seven of these chapters are essentially devoted to the Fourier series/transform, discrete Fourier transform, fast Fourier transform (FFT), and applications of the FFT in the area of spectral estimation. Chapters 8 through 10 deal with many other discrete-time transforms and algorithms to compute them. Of these transforms, the KarhunenLoeve, the discrete cosine, and the Walsh-Hadamard transform are perhaps the most well-known. A lucid discussion of number theoretic transforms i5 presented in Chapter 11. This reviewer feels that the authors have done a fine job of compiling the pertinent material and presenting it in a concise and clear manner. There are a number of problems at the end of each chapter, an appreciable number of which are challenging. The authors have included a comprehensive set of references at the end of the book. In brief, this book is a valuable contribution to the general areas of signal processing and communications. It can be used for a graduate level course in perhaps two ways. One would be to cover the first seven chapters in great detail. The other would be to cover the whole book by focussing on different topics in a selective manner. This book  by  Elliott  and Rao  is extremely  useful to researchers/engineers who are working  in the areas of signal processing and communications. It i s also an excellent reference book, and hence a valuable addition to one’s library

Multirate digital signal processing

An optimal filter design technique for the prefilter moving target indication (MTI) method used in synthetic aperture radar (SAR) systems is presented. The technique is general, so that the data resampling ratio can be an arbitrary rational number. The digital filters have linear phase and are based on a two-stage design process involving an interpolation and a decimation. A filter is designed for each stage and the final optimized design is the convolution of the single stage filters. The proposed filters are sued when the pulse repetition frequency is a rational multiple of the clutter bandwidth. The filters show good clutter cancellation and minimal aliased overlap between MTI bands. An example is provided which demonstrates the effectiveness of the design technique. >
