دانلود کتاب ADSL,VDSL and multicarrier modulation

The state of the art of multicarrier modulation for the transmission of high-speed data With DSL technology poised to provide the fastest means of Internet access for years to come, there is a growing need for practical information on running xDSL services over existing telephone lines. Communications expert John Bingham draws on three decades of intimate involvement with data transmission research to provide a complete guide to the state of the art and future direction of multicarrier modulation (MCM)-one of the key methods for high-speed data transmission today. Geared to designers and system planners working with DSL modems, Internet access, and telephony, ADSL, VDSL, and Multicarrier Modulation presents everything engineers and programmers need to design MCM modems, understand current implementations, and formulate strategies for future improvements and research. Detailed, thoroughly logical coverage includes:* Precise descriptions of problems associated with the transmission of high-speed data and how to solve them* Clear explanations of the DSL medium and how to calculate its capacity* Discussions of the theory as well as advantages and disadvantages of MCM* A link between physical and higher layers for Internet access* Essential yet hard-to-find information on spectral management* Over 100 tables and graphs of data rates illustrating the theory, plus MATLAB program listings
