From the Publisher: The Verilog Programming Language Interface is a powerful feature of the Verilog standard. Through this interface, a Verilog simulator can be customized to perform virtually any engineering task desired, such as adding custom design debug utilities, adding proprietary file read/write utilities, and interfacing bus functional C language models to a simulator. This book serves as both a user's guide for learning the Verilog PLI, and as a comprehensive reference manual on the Verilog PLI standard. Both the TF/ACC ("PLI 1.0") and the VPI ("PLI 2.0") generations of the PLI are presented, based on the IEEE 1364 Verilog standard. The second edition of this book adds detailed coverage of the many enhancements added in the latest IEEE 1364-2001 Verilog standard ("Verilog-2001"). A CD is included, with the C source code, Verilog HDL test cases and simulation result logs for more than 75 complete PLI examples.

From the Publisher: Orthogonal Frequency Division Multiplexing (OFDM) has become the technology of choice for broadband communication in a wireless multipath environment. For instance, it will be used in next generation wireless local area networks (WLANs) and broadband fixed wireless access networks. Although the theory of OFDM is well developed, implementation aspects of OFDM systems remain a challenge. Wireless OFDM Systems brings together the broad and extensive experience of the editor and contributors by providing a comprehensive overview of OFDM implementation issues and OFDM based WLAN systems. The book starts with a discussion of indoor propagation channels, followed by an overview of the basics of OFDM, HIPERLAN/2 and IEEE 802.11a standards. Next, readers are lead through a complete design cycle of an OFDM transceiver, starting with channel estimation and synchronization functionality, and carried through to actual realizations. The different influences of the radio front-end on OFDM communication performance are detailed in the next chapters as well as many OFDM practical problems related to non-linear power amplifiers. The authors conclude with illustrations of several practical implementations involving wireless OFDM transceivers. Wireless OFDM Systems is a must have reference work for wireless communication designers who are building wireless OFDM transceivers.

At present, the expansion of tetherless communications is a technological trend surpassed perhaps only by the explosive growth of the Internet. Wireless systems are being deployed today mainly for telephony, satisfying the ind- trialized nations''appetite for talk-on-the-go, and providing much-needed communications infrastructure in developing countries. The desire for wi- less access to the Internet is starting to add fuel to the growth of tetherless communications. Indeed, the synergy of wireless and Internet technologies will lead to a host of exciting new applications, some of which are not yet envisioned. Future-generation wireless systems will achieve capacities much higher than the systems of today by incorporating myriad improvements. These in- vations include transmission in higher-frequency bands, “smart antennas”, multi-user detection, new forward error-correction techniques, and advanced network resource-allocation techniques. The term “smart antenna” usually refers to the deployment of multiple antennas at the base-station site, coupled with special processing of the m- tiple received signals. Smart antennas can adaptively reject co-channel int- ference and mitigate multipath fading, and have been identified by many as a promising means to extend base-station coverage, increase system capacity and enhance quality of service.

For four decades the evolution of integrated circuits has followed Moore's law, according to which the number of transistors per square millimeter of silicon doubles every 18 months. At the same time transistors have become faster, making possible ever-increasing clock rates in digital circuits. This trend seems set to continue for at least another decade without slowing down. Thus, in the near future the processing power of digital circuits will continue to increase at an accelerating pace. For analog circuits the evolution of technology is not as beneficial. Thus, there is a trend to move signal processing functions from the analog domain to the digital one, which, besides allowing for a higher level of accuracy, provides savings in power consumption and silicon area, increases robustness, speeds up the design process, brings flexibility and programmability, and increases the possibilities for design reuse. In many applications the input and output signals of the system are inherently analog, preventing all-digital realizations; at the very least a conversion between analog and digital is needed at the - terfaces. Typically, moving the analog-digital boundary closer to the outside world increases the bit rate across it. In telecommunications systems the trend to boost bit rates is based on - ploying widerbandwidths and a higher signal-to-noise ratio. At the same time radio architectures in many applications are evolving toward software-defined radio, one of the main characteristics of which is the shifting of the anal- digital boundary closer to the antenna.
