Book Description
The Mammoth Book of Codeword Puzzles is a truly bumper collection of these hugely popular puzzles - also known as codewords, cipher crosswords and cipher word puzzles. There are also some fun variations in the form of dropouts, keywords, coded quotes and long diversions. In a codeword puzzle, each grid is made up of numbered squares, with each number corresponding to a letter of the alphabet. A few letters are given, but the rest must be discovered by using logic and word power to crack the code. HOURS OF STIMULATING PUZZLE FUN!

Book Description
200 brand new compelling and addictive word and number puzzles from The Times. Appearing daily in the newspaper, Codeword is the cracking alternative to Su Doku and Crosswords. The concept is simple: each number represents a letter, so, starting with the solved letters, use your logic and vocabulary to reveal more letters, form words, and then crack the code! The most difficult puzzles for top solvers contain no solved letters so you need to employ all your logical strategies to crack those. The Codeword series is so popular because you don't need any prior knowledge, unlike a crossword. You can just pick up a pen and get puzzling. It steadily increases your vocabulary, as the difficulty slowly grows as you progress through the book, and even though you'll be working your brain, it's the perfect way to unwind.

Book Description
Fun Codeword Puzzle Book for Adults - Can you crack the code? Codeword puzzles are similar to crossword puzzles: The difference is that there are no clues provided. Instead, every letter of the alphabet is replaced by a number from 1-26. For instance, the letter "F" might be replaced by number 15 and the letter "R" by number 4. And your task is to crack the code by figuring out which letter is represented by which number. Happy code breaking! Key features of the puzzle book: 120 Codeword Puzzles Book size: 8,5 x 11 inch (ca. DIN A4) Including instructions Solutions at the back of the puzzle book The codeword puzzle book is the perfect gift for adults and seniors who love brain jogging and mental excercises.

Book Description
Codeword a Day 2021 * Please note Codeword a Day 2022 has also now been released * Welcome to this fantastic book of 366 codeword puzzles, one for every day of the year in 2021 - and a bonus puzzle for 1st January 2022. If you are looking for a gift for a puzzle fan, or enjoy solving codewords yourself, look no further than this collection of brand new crossword-style code-cracking puzzles, for a brand new year. This fantastic collection is sure to keep any codewords fan on their toes and will even help to train the novice puzzler into an expert! The puzzles are dated for every day of the year from 1st January 2021 onwards, so there's no chance of losing track and with two puzzles a page, there's plenty of room to take notes if needed. Every puzzle has a single solution, is played on a 13x13 grid, and has three hint letters to get you started. We recommend you start by placing these into the grid. That may reveal other words straightaway. If not, it is often worth trying to place common letters such as the E early on to help with your code breaking. The three most common letters in English are E, T and A: remember that counting how many times each number appears in the grid can be a good indication as to the number that represents these letters. If you get stuck along the way, take a look towards the back of the book where you will find all of the solutions to help you. We hope that you, or the puzzle lover you buy this book for, enjoys cracking the codewords. All of our puzzle books are printed on very high quality paper making the puzzle experience all the more enjoyable!

Quasi-orthogonal Space-time Block Code

Author: Yong Liang Guan
Publisher: World Scientific
ISBN: 1908979100
Category : Technology & Engineering
Languages : en
Pages : 209

Book Description
Quasi-Orthogonal Space-Time Block Code presents an up-to-date, comprehensive and in-depth discussion of an important emerging class of space-time codes, called the Quasi-Orthogonal STBC (QO-STBC). Used in Multiple-Input Multiple-Output (MIMO) communication systems, they provide transmit diversity with higher code rates than the well-known orthogonal STBC (O-STBC), yet at lower decoding complexity than non-orthogonal STBC. This book will help readers gain a broad understanding of the fundamental principles as well as the state-of-the-art work in QO-STBC, thus enabling them to appreciate the roles of QO-STBC in future broadband wireless systems and to inspire further research./a

List Decoding of Error-Correcting Codes

Author: Venkatesan Guruswami
Publisher: Springer Science & Business Media
ISBN: 3540240519
Category : Computers
Languages : en
Pages : 354

Book Description
This monograph is a thoroughly revised and extended version of the author's PhD thesis, which was selected as the winning thesis of the 2002 ACM Doctoral Dissertation Competition. Venkatesan Guruswami did his PhD work at the MIT with Madhu Sudan as thesis adviser. Starting with the seminal work of Shannon and Hamming, coding theory has generated a rich theory of error-correcting codes. This theory has traditionally gone hand in hand with the algorithmic theory of decoding that tackles the problem of recovering from the transmission errors efficiently. This book presents some spectacular new results in the area of decoding algorithms for error-correcting codes. Specificially, it shows how the notion of list-decoding can be applied to recover from far more errors, for a wide variety of error-correcting codes, than achievable before The style of the exposition is crisp and the enormous amount of information on combinatorial results, polynomial time list decoding algorithms, and applications is presented in well structured form.

Fundamentals of Error Correcting Codes is an in-depth introduction to coding theory from both an engineering and mathematical viewpoint. As well as covering classical topics, there is much coverage of techniques which could only be found in specialist journals and book publications. Numerous exercises and examples and an accessible writing style make this a lucid and effective introduction to coding theory for advanced undergraduate and graduate students, researchers and engineers, whether approaching the subject from a mathematical, engineering or computer science background.

The Art of Error Correcting Coding

Author: Robert H. Morelos-Zaragoza
Publisher: John Wiley & Sons
ISBN: 0470035692
Category : Technology & Engineering
Languages : en
Pages : 278

Book Description
Building on the success of the first edition, which offered a practical introductory approach to the techniques of error concealment, this book, now fully revised and updated, provides a comprehensive treatment of the subject and includes a wealth of additional features. The Art of Error Correcting Coding, Second Edition explores intermediate and advanced level concepts as well as those which will appeal to the novice. All key topics are discussed, including Reed-Solomon codes, Viterbi decoding, soft-output decoding algorithms, MAP, log-MAP and MAX-log-MAP. Reliability-based algorithms GMD and Chase are examined, as are turbo codes, both serially and parallel concatenated, as well as low-density parity-check (LDPC) codes and their iterative decoders. Features additional problems at the end of each chapter and an instructor’s solutions manual Updated companion website offers new C/C ++programs and MATLAB scripts, to help with the understanding and implementation of basic ECC techniques Easy to follow examples illustrate the fundamental concepts of error correcting codes Basic analysis tools are provided throughout to help in the assessment of the error performance block and convolutional codes of a particular error correcting coding (ECC) scheme for a selection of the basic channel models This edition provides an essential resource to engineers, computer scientists and graduate students alike for understanding and applying ECC techniques in the transmission and storage of digital information.
