If you're a mobile communications engineer considering software radio solutions, this practical resource is essential reading. It covers systems design and partitioning all the way from the antenna to the management and control software. Various options for hardware are provided including a look at current and state of the art silicon technologies such as A/D & D/As, DSPs, FPGAs, RCPs, ACMs & digital frequency up/down-converters.

This reference offers practical explanations of the full range of radio frequency integrated circuits (RFICs). It focuses mainly on bipolar technology to demonstrate circuits, but CMOS is included as well. By emphasizing working designs, it seeks to transport the reader into the authors' own RFIC lab so that you can understand the function of each design detailed in the text. Among the RFIC designs examined are RF integrated LC-based filters, VCO automatic amplitude control loops, and fully-integrated transformer-based circuits, as well as image reject mixers and power amplifiers.

The book addresses IPsec’s major aspects and components to help you evaluate and compare features of different implementations. It gives you a detailed understanding of this cutting-edge technology from the inside, which enables you to more effectively troubleshoot problems with specific products. Based on standards documents, discussion list archives, and practitioners’ lore, this one-of-a-kind resource collects all the current knowledge of IPsec and describes it in a literate, clear manner.

Internet and wireless technologies are converging towards an exciting future that we've only begun to realize. For professionals who have a background in the Internet or in mobile telephony - but not in both - this integrated "how it works" guide offers a practical understanding of wireless Internet communications, the technology components involved, and how they fit and work together.
