I bought this book with great expectations. It covered all relevant subjects related to DSL. Even the first chapter summarizing POTs cable plant was encouraging. But, the book is horrible. Things are just thrown together without explaining clearly any of the subjects. Despite all the bad reviews you might be tempted to buy this book because there is not another book that covers all the DSL related material included in this book. Don't! There are many good books on communication theory that cover equalization, echo cancellation, adaptive filtering, error correcting codes, noise, etc. It might be necessary to read some of these general books + a simple book on DSL to cover the same material as this book does. |
