The GSM system is undoubtedly the most successful second-generation digital mobile radio system. One of the key factors for this exceptional performance is the constant evolution of the GSM system and its derivatives. GSM: Evolution towards 3rd generation systems addresses new concepts in the GSM system, dealing both with standardized features as well as with theoretically and technologically feasible improvements which contribute to evolutionary changes in general. Ongoing efforts in GSM standardization are focused on Phase 2+ with gradual additions for a fast and modular evolution. Speech remains the prime service of cellular systems, with ongoing work on spectral efficiency taking into account the tradeoff between cost of the system and transmission quality. Most of the notable results from novel speech service implementations are addressed herein such as new EFR speech codec and Advanced Speech Cell Items (ASCI). Data capability in Phase 2+ has been covered under General Packet Radio Service (GPRS) and High-Speed Circuit Switched Data (HCSD) work items. Initiatives under CAMEL cover intelligent networking (IN) within the GSM framework. Dual mode operation in GSM includes not only dual-band solutions but also inter-networking with other systems like DECT or satellite systems. Numerous specific wireless applications such as inbuilding communications, WLL, etc., have also been developed based on GSM. To support the required changes a number of issues have to be solved in the radio part of the system. Deployment of adaptive antenna arrays for enhanced quality, interference suppression techniques and slow frequency hopping are among the techniques presented in the GSM framework. Dynamic evolution of GSM presents a platform for the introduction of UMTS. Presently, efforts are directed towards the standardization of the UMTS air interface in ETSI. Major trends in progress towards new radio interfaces are outlined including contributions from pan-European projects such as ATDMA, which was carried out under the RACE II framework, and the ACTS project AC090 FRAMES. GSM: Evolution towards 3rd generation systems comprises a collection of specially written contributions from GSM specialists. The information presented is essential reading for all researchers, engineers and managers working on GSM and third generation wireless systems. This book covers the most important advances in GSM that will have lasting impact on the system influencing third generation wireless systems.

A New York Times Editors' Choice Pick "Kennedy and King is an unqualified masterpiece of historical narrative . . . A landmark achievement." -- Douglas Brinkley, New York Times bestselling author of Rosa Parks Kennedy and King traces the emergence of two of the twentieth century's greatest leaders, their powerful impact on each other and on the shape of the civil rights battle between 1960 and 1963. These two men from starkly different worlds profoundly influenced each other's personal development. Kennedy's hesitation on civil rights spurred King to greater acts of courage, and King inspired Kennedy to finally make a moral commitment to equality. As America still grapples with the legacy of slavery and the persistence of discrimination, Kennedy and King is a vital, vivid contribution to the literature of the Civil Rights Movement.

NEW YORK TIMES BESTSELLER! Washington insiders operate by a proven credo: When a Peter Schweizer book drops, duck and brace for impact. For over a decade, the work of six-time New York Times bestselling investigative reporter Peter Schweizer has sent shockwaves through the political universe. Clinton Cash revealed the Clintons’ international money flow, exposed global corruption, and sparked an FBI investigation. Secret Empires exposed bipartisan corruption and launched congressional investigations. And Throw Them All Out and Extortion prompted passage of the STOCK Act. Indeed, Schweizer’s “follow the money” bombshell revelations have been featured on the front pages of the New York Times and the Wall Street Journal, and regularly appear on national news programs, including 60 Minutes. Now Schweizer and his team of seasoned investigators turn their focus to the nation’s top progressives—politicians who strive to acquire more government power to achieve their political ends. Can they be trusted with more power? In Profiles in Corruption, Schweizer offers a deep-dive investigation into the private finances, and secrets deals of some of America’s top political leaders. And, as usual, he doesn’t disappoint, with never-before-reported revelations that uncover corruption and abuse of power—all backed up by a mountain of corporate documents and legal filings from around the globe. Learn about how they are making sweetheart deals, generating side income, bending the law to their own benefits, using legislation to advance their own interests, and much more. Profiles in Corruption contains tomorrow’s headlines.
