Fundamentals of Voice-Quality Engineering in Wireless Networks

Network operators are faced with the challenge of maximizing the quality of voice transmissions in wireless communications without impairing speech or data transmission. This book provides a comprehensive survey of voice quality algorithms features interactions and trade-offs at the device and system levels. The book 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. A ''troubleshooting and case studies'' chapter provides a useful approach to identifying and solving network impairments. 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.
