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. Further resources, including a range of audio examples, are available online at www.cambridge.org/ 9781107407183.

A suspense-thriller about a nightmare scenario-a countdown to a Mumbai-style attack on U.S. soil, where the FBI, the Israeli Mossad, the US-based Iranian clandestine terror network, and the Islamic Jihad fraternity, all engaged in a timeless conflict, which plays out to a crescendo that comes to a head before the dramatic conclusion. The story offers an ample dose of realism, a cast of intense characters who engage in love, lust, and violence. It portrays the Jihad culture with its rationale and the volcano that breeds an irrational obsession with death. Moreover, it builds on the Jihadists' motivation for targeting so many innocents and exploiting the victims' massacre as a stepping-stone to their dream of eternal paradise next to Allah's throne. The real question is not whether Jihad terrorists' plots will ever cease to emerge-there is no chance of that. The question the book seeks to answer is, will the next one be stopped before it's too late?
