This book provides a comprehensive survey of voice quality algorithms, features, interactions, and trade-offs, at the device and system level. Using a practitioner rather than algorithm-designer angle, this book is unique. It elaborates on the root cause of impairments and ways for resolving them, as well as methodologies for measuring and quantifying voice quality before and after applying the remedies. The key issues are exemplified using case studies. Avoiding complex mathematics, the approach is based on real and sizable field experience supported by scientific and laboratory analysis. This title is suitable for practitioners in the wireless communications industry and graduate students in electrical engineering.
