Multirate Signal Processing for Communication Systems: Current Practice and Next Generation Techniques fredric j harris

Multirate signal processing can reduce costs and improve performance in applications ranging from laboratory instruments to cable modems, wireless systems, and consumer entertainment products. This book offers the first systematic, clear, and intuitive introduction to multirate signal processing for working engineers and system designers.

The author uses extensive examples and figures to illuminate a wide range of multirate techniques, from basic resampling to leading-edge cascade and multiple-stage filter structures. Along the way, he draws on extensive research and consulting experience to introduce processing itricksi shown to maximize performance and efficiency.

Coverage includes:

• Effective sampling and resampling in time and frequency domains

Preface

Digitalsignal processing (DSP) has become a core body of material in undergraduateelectrical engineering programs. Several threads branch from this core toenable related disciplines, such as communication systems, source coding,multimedia entertainment, radar, sonar, medical and laboratory instruments, andothers. Multirate signal processing isone of these major threads. Multirate signal processing is the body of materialthat deals with concepts, algorithms, and architectures that embed sample ratechanges at one or more sites in the signal flow path.

There are two reasons to include multirate signal processing in thesolution of a particular signal-processing task. The first is reduction in costof the implementation. The second is enhanced performance of theimplementation. We might also include a third, personal incentive, which is,that it is fun to apply clever concepts to solve problems. We can hardlycomplete a multirate DSP design without a smile and the accompanying thought,“Boy, this is neat!”

Traditional concepts developed in the DSP world are the same asthose developed in the analog-processing world. In both domains we learn anduse concepts such as convolution, Fourier transforms, transfer functions, polesand zeros, and others. When required to distinguish the two approaches we usethe qualifier “discrete” when discussing the DSP version of thesefundamental concepts. The reason the two approaches are so similar is that theyboth emphasize linear time invariant (LTI) systems for which the toolsof analysis and synthesis are well developed.

Multirate signal processing brings to the designer an importanttool not available to the traditional DSP designer, who to the first orderapplies DSP techniques to emulate analog systems. We note that the interfacebetween the two versions of the world, continuous and discrete, is the samplingprocess. In the traditional DSP perspective, the sample rate is selected tosatisfy the Nyquist criterion but is otherwise incidental to the problem. Inmultirate signal processing, selection and modification of the sample rate areprimary considerations and options in the signal processing chain. The op...

5.0 out of 5 stars The "Zen" of Advanced Digital Signal Processing!, September 1, 2004

This review is from: Multirate Signal Processing for Communication Systems (Hardcover)

Several years ago, my company hired Fred Harris as a consultant to help create an extremely complex multi-channel digital receiver. As it turned out, we could not have found a better candidate. Fred doesn't just offer state-of-the-art processing techniques - many of which he himself has developed - his pragmatic focus on efficiency and real-world implementation is truly refreshing.

This superb book delivers that same approach and philosophy in a very readable, approachable text. Unlike the vast majority of books in the field, which teach only the mathematics of signal processing, Fred teaches you what it really means, and how to make it work. You'll learn extremely efficient signal processing techniques, but even more importantly, you'll gain a much deeper understanding of digital communications that will change the way you approach systems design. From my perspective, this is quite simply the best book available for practitioners who are creating advanced digital communications systems.

5.0 out of 5 stars The most valuable text ever for Multirate filters and DSP, May 5, 2004

By A Customer

This review is from: Multirate Signal Processing for Communication Systems (Hardcover)

With excellent clarity, multirate filters are described, derived and then implemented. Any DSP filter designer will benefit from this book, advanced or not. Also, a series of proprietary filter structures have been 'donated' to the DSP community in this book, wherein some of the most effecient filter structures I've ever seen are explained and implemented.

This review is from: Multirate Signal Processing for Communication Systems (Hardcover)

I purchased the book "Multirate Signal Processing for Communication Systems" by Fredric J. Harris because it contained an entire chapter devoted to the Cascaded Integrator Comb (CIC) filter. This filter, sometimes referred to as the Hogenauer Filter, can be used to implement efficient multirate decimation and interpolation filters for large sample rate changes.

To date no author of any book or technical paper that I am aware of has ever been able to explain the mathematics of pruning bits in each of the N stages of a CIC decimation filter design. I had high hopes that Harris's book would finally be the one book that would go where no book has gone before.

Unfortunately the book could not be previewed on Amazon so I bought the book on faith alone. I ended up being disappointed. In his treatment of CIC filters that are used for sample rate decimation he presents an obtuse equation with 6 variables that is supposed to explain something about determining the number of bits that can be pruned from each stage of an N stage CIC decimation filter. The problem is, this equation was presented right out of the blue, without any definition of what the 6 variables were. Nothing preceded this equation, or followed this equation, that was relevant to explaining what the equation was or how to interpret it. Somehow the reader is supposed to magically figure out how this equation and all 6 of its undefined variables, is relevant to CIC bit pruning. I held out some hope that this equation had been derived and explained in previous chapters, so I spent several hours searching the book from the beginning to the end for any material that was remotely connected to that equation. I had no success.

I have read many papers and many texts written by many authors that dealt with CIC filters. Without exception all the authors arm waved and side stepped this critical bit pruning topic, but this is the first time I have ever seen anything as crazy as this.

Since I bought the book, I went ahead and read the remainder to see if it contained any new material applicable to the field of multirate digital signal processing. It did not.

My impression of this book is that it is well suited for engineering managers who need a quick and glossed over summary of multirate DSP basics and buzz words so that they can sit in a conference room, nod their heads, and give the appearance of understanding what a design engineer is presenting.

This book really isn't of much use to an "in the trenches" DSP design engineer. It contains no detailed engineering design information, no valuable design examples, no insight to real world problems, and it contains no real world design issues and their solutions. There are no illustrative engineering applications presented that utilize multi rate signal processing.

The book does contain a lot of illustrations that look to be transplanted Mat Lab plots but there is not a great deal of associated text or mathematics that explains the intent of these plots.

Even though my review is negative, I hope that it is presented in a positive way. I guess I am disappointed because I paid about 78 dollars for this book and I will never get any meaningful engineering use from it.

In summary, this book is not a useful resource for a DSP design engineer. For practicing design engineers involved in Multi Rate designs, I would recommend the technically excellent book by Rabiner and Crochiere titled "Multirate Digital Signal Processing", published by Prentice Hall 1983. It is a bit difficult to read, but if you sit down with a pencil and paper and work the examples, study the equations, and make these equations meaningful by drawing the DSP architectures that they describe you will come away with a deep understanding of the subject.
