Simulation of Communication Systems: Modeling, Methodology and Techniques (Information Technology: Transmission, Processing and Storage) Review

Simulation of Communication Systems: Modeling, Methodology and Techniques (Information Technology: Transmission, Processing and Storage)
Average Reviews:

The second edition is a much-improved version compared to the first one. More details are added -- which makes it easy to follow. Anyone who is doing system simulation or performance analysis should have one around. I would have rated it a 5-star if the authors should have included some of the algorithms in a CD to save reader's time.

Since the first edition of this book was published seven yearsago, the field of modeling and simulation of communication systems hasgrown and matured in many ways, and the use of simulation as aday-to-day tool is now even more common practice. With the currentinterest in digital mobile communications, a primary area ofapplication of modeling and simulation is now in wireless systems of adifferent flavor from the `traditional' ones. This second edition represents a substantial revision of the first,partly to accommodate the new applications that have arisen. Newchapters include material on modeling and simulation of nonlinearsystems, with a complementary section on related measurementtechniques, channel modeling and three new case studies; aconsolidated set of problems is provided at the end of the book.

Statistical and Adaptive Signal Processing: Spectral Estimation, Signal Modeling, Adaptive Filtering and Array Processing (Artech House Signal Processing Library) Review

I believe this book is destined to become the "classic" graduate text used to teach statistical and adaptive digital signal processing.
If you enjoyed the introductory text "Digital Signal Processing" by Proakis and Manolakis (Prentice-Hall 1996), I think you will enjoy this book by Manolakis, Ingle, and Kogon. It is written in a similar style, with an introduction to each chapter previewing the material to be covered, a logical development of the material including examples, and a conclusion summarizing the high points of the material covered.
At chapter's end, there is a set of well thought out exercises ranging from easy to difficult. There are no answers to the problems in the back of the book, but there are enough examples in each chapter that one should be able to tackle most of the exercises. Some of the exercises require MATLAB. The authors have written some custom MATLAB functions which are available from the publisher as an e-Mail attachment.
I would say this book is written at the graduate level and requires knowledge of several disciplines: 1) DSP- At the level of Proakis + Manolakis intro text (cited above). 2) Linear Algebra- Cramer's rule, LDU factorization, eigenvalues, eigenvectors, Hermitian and Unitary matrices, etc. 3) Statistics- Random variables, averages, variances, estimators, sampling distributions, auto- and cross- correlations. I had no previous knowledge of stochastic processes, and was able to pick up enough from Chapter 3 to get through the rest of the book.
This book is, above all, a mathematical text written for engineers. It describes the theory and equations underlying statistical filters.
There is a lot of meat in each section. I typically had to read each section an average of 3 times for it to sink in.
With help from Figure 1.2.8 of the book, it covers the following material:
Chapter 1- Introduction to applications of spectral estimation, signal modeling, adaptive filtering, and array processing.
Chapter 2- Review of discrete-time signal processing.
Chapter 3- Review of random vectors and signals: properties, linear transformations, and estimation.
Chapter 4- Random signal models with rational system functions (AR, MA, ARMA, ARIMA).
Chapter 5- Nonparametric spectral estimation.
Chapter 6- Optimum filters and predictors -- matched filters (including Wiener) and eigenfilters.
Chapter 7- Algorithms and structures for optimum filtering (including algorithms of Levinson, Levinson-Durbin, Schur, Kalman, ...)
Chapter 8- Least-squares filtering and prediction (normal equations, orthogonalization, SVD).
Chapter 9- Signal modeling and parametric spectrum estimation.
Chapter 10- Adaptive filters: Design, performance, implementation, and applications (includes steepest descent, LMS, NLMS, CRLS, QR-RLS, fast RLS, fast Kalman, RLS lattice-ladder, ...).
Chapter 11- Array processing: theory, algorithms, and applications.
Chapter 12- Higher order statistics, blind deconvolution and equalization, fractional and fractal random signal models.
Appendix B includes the clearest, most graphic example of LaGrange multipliers I have ever seen!
Note that this book deliberately leaves out the following topics because it is NOT meant to be a text that covers ALL of ADVANCED DSP: Multirate DSP, Wavelets, etc.
I highly recommend this book to anyone involved in spectral estimation, signal modeling, adaptive filtering, or array processing.

Good book for looking at the mathematics behind biomedical signal processing. If your going to use Matlab in conjunction with your study of this book, I used "Biosignal and Biomedical Image Processing: Matlab-Based Applications," by John L. Semmlow.

Modeling Random Processes for Engineers and Managers Review

Modeling Random Processes for Engineers and Managers
Average Reviews:

Author James Solberg claims that his book has a non standard presentation for probability and random processes. He is absolutely right! For example, he devotes a whole chapter (Chapter 2) to modeling Markov chains, before doing any of the usual calculation methods (chapter 3).
In other books, a small amount of such material would appear as examples or exercises. But Solberg deems it worthy of a whole chapter, and he specifically states properties that would normally be overlooked. For example, he talks about converting count data into transition matrices, he talks about different possible ways of defining step size, he introduces lumpability to reduce the size of the state space.
The book is full of examples,chosen to illustrate practical uses of the material, or selected to add understanding. This book is student friendly. I lent my copy to a graduate student and after returning the book, he commented that the book greatly improved his understanding of stochastic processes. The book is at a lower level than many other books on the subject, but not much lower. The author's years of experience enable him to recognize where a student would normally have difficulties and the author takes steps to add explantion to enhance understanding. Chapter 8 gives a new path counting method to find limiting probabilities for Markov chains and continuous time Markov processes. Chapters 6 and 7 deal with queueing and queueing networks. The book is consistently well written. I think that this is a splendid book for a nonprobabilist to become introduced to the material. I have never met James Solberg, but the queue on the front cover includes a cheerful man who seems older than the others. I hope that man is Solberg. Even if not, the smile on the man's face comes through in the writing of the book.

By reducing mathematical detail and focusing on real-world applications, this book provides engineers with an easy-to-understand overview of stochastic modeling. An entire chapter is included on how to set up the problem, and then another complete chapter presents examples of applications before doing any math. A previously unpublished computational method for solving equations related to Markov processes is added. The book shows how to add costs or revenues to the basic probability structures without much additional effort. In addition, numerous examples are included that show how the theory can be used. Engineers will also find explanations on how to formulate word problems into the models that the math worked on.
